Form translation component should be always on top

[michnov]

Even though the Outbound/Form translation component cannot be implemented as a native panel in the chrome (since it is not allowed for extensions to make use of XUL/XPCOM), it should act so and resemble it as much as possible. One of the expected features is that it always stays on top.

The following webpages show that in the implementation that I tested (https://github.com/mozilla/firefox-translations/actions/runs/1458463171), it is not always the case.

Please let me know if there is an updated version of the extension that I should use.
My version of Nightly: 97.0a1

Another case:

Install current extension

Click translate
Click Yes to enable translations of forms (and wait an unusually long time for "Loading form translation")
Click "Ask a question." lower down in the page to open a modal dialogue.
Click on the textarea.

This was fixed by 2602bad. I couldn't reproduce any of these behaviors with that patch.
