More STR in https://github.com/mozilla-mobile/fenix/issues/14884

The STR is;

1. Zoom any page
2. Scroll to the last word of a sentence in a text, you can try with the one at the end of this comment for example.
3. Long tap to select the word
4. The browser scrolls so that the top left corner of the text is at the top left corner of the browser window.
5. If it doesn't happens try with a different word, text or page.

Unfortunately I can't reproduce the issue though. (And in my sense, it's an issue in scrollIntoView implementation?) If this could be easily reproducible, a reduce test case would be quite helpful.

Emily, is this reproducible on your end? If so, is it also reproducible on desktop Firefox with zooming?

Adina, honestly I am not sure you are the right person to ask something on mobile testings, but I am pretty sure you have some Android devices to be able to test. Can you please give your hand to test this issue? It's been a while since this issue filed so maybe it was already fixed? Thanks!

I tested this issue with Motorola Moto G9 plus (Android 11) on Nightly 110.0a1 - 06/01/2023 and could not reproduce it. I followed the main steps with https://www.developpez.com/actu/308380/Votre-historique-de-navigation-peut-vous-identifier-de-maniere-precise-d-apres-une-etude-menee-par-les-chercheurs-de-Mozilla/ link and also with the steps in Comment 2.
