Fix navigation warnings on autotest manager and starter file manager pages, closes 7641

[philipkukulak]

Proposed Changes

On the Settings > Automated Tests page, a warning should pop up if a user attempts to navigate away from the page after making changes and before saving them.

Currently, it appears even after the user has saved their changes. This happens because the Settings > Automated Tests page is rendered with react, which is rendered after the jquery click handler in _navigation_warning.js.erb is registered: submit_clicked can never be flipped to true because the submit button doesn't exist when that handler is registered.

Furthermore, the window.onbeforeunload handler as defined in the _navigation_warning.js.erb partial has no awareness of the Automated Tests page react structure. The page and the partial within it are tracking 'dirtiness' in separate state variables.

With help from claude, the cleanest fix is to override the window.onbeforeunload handler in autotest_manager.jsx and to gate the initialization of the page so that fetchData doesn't instantly 'dirty' the page when react fires onChange upon first receipt of existing form data.

The fix for the Settings -> Starter Files page is far simpler, since it is not rendered using react: we bind the handler to .on('click', ...) instead.

Questions and Comments

I had the thought that we could also take this a step further and track changes to the page that are 'undone', e.g. checking a box and then unchecking it, and make sure the navigation warning doesn't pop up in that case. I came to the judgment that this would bloat the code more than we could justify an improvement so slight.

I also did not touch the Settings -> Starter Files page (on which this bug is also present) but if it is decided upon review that we'd like to bundle that fix into this PR, I would be happy to do so. Applied this fix to the Settings -> Starter Files page.

Nice work, @philipkukulak. I left one inline comment, and also it seems like you should now be able to remove the loading of the _navigation_warning.js.erb partial from this page.

Please go ahead and also make the same change to the starter files page.

[david-yz-liu]

Overall I don't think this _initializing attribute is necessary. You can check the current value of this.state.formData before doing any updates, treating Object.keys(this.state.formData).length === 0 as the "initializing" condition.

[philipkukulak]

Wouldn't Object.keys(this.state.formData).length > 0 if any form data already exists, e.g. some tester is already configured? That would mark the page 'dirty' by default whenever there's persistent data. I'm thinking of 'initialization' as the initial fetch for page contents rather than the contents of the page itself.

[david-yz-liu]

I'm also considering "initialization" as the initial fetch. The initial state of this component sets formData: {}. After the data is fetched this will change. (For a new assignment I suppose it's possible the fetched value may be {} as well, I'm not sure. If so, you can change the initial formData state to null instead to disambiguate it.)

[philipkukulak]

Ahhh okay I think I understand. I'll re-request review once I pushed these changes. Thanks David.

[philipkukulak]

Removed the _navigation_warning partial from Settings -> Automated Tests since everything is handled by a react component now. Applied the fix to the Settings -> Starter Files page (much easier to fix here since there is no react on that page.) Also changed the initialization gate on the Settings -> Automated Tests per David's recommendations. Tested it locally. It works! Pretty cool.

Note that overall test coverage has gone down because we've created a new test suite (autotest_manager.test.jsx) that only tests our bug fix.

This change is quite different from the one for the autotest manager and not what I expected (this file is used by other views as well, so should not be changed).

The starter file page does use React, with the root component being StarterFileManager. Please make the same type of change you made for the AutotestManager in that component.
