Description of Code / Doc Changes

I have not merged the latest version of the main branch into this PR because it is currently failing its own tests (specifically, the geolocation and FxA tests). This branch is based on the last stable commit before those unrelated failures were introduced.

Once main is fixed, I can rebase or merge the latest changes into this PR if needed.

---

• Creates a new automated test for opening a bookmark in a new tab (Bug 1976272).
• Adds the correct element ID for the "Open in New Tab" context menu item to context_menu.components.json.
• Implements an explicit wait (WebDriverWait) in the test to fix a race condition and ensure reliability.

This picked up some l10n_CM testing stuff, which caused some failures and merge conflict. If you merge main again. Then address the failure in your test, on Mac, in checking for number of tabs. The fact your test passed on Windows and Linux indicates a possible race condition. I think it may be happening from line 34 and 35 of your tests. Add a wait in between those two lines. "tabs.wait_for_num_tabs(2)" to ensure the new tab, of line 34, is opened before the next test step.

Lastly, when you add a new selector, like you have in modules/data/context_menu.components.json, please add the appropriate entry into the SELECTOR_INFO.md (In this case, insert the new selector documentation after line 1776).

Nevermind my theory on there being a race condition. Don't implement that suggested fix. Instead see next review comment inline....

Tried to merge main and push but git wanted to create a new PR. my git-fu is weak. :(. So we now have PR 755 for this.
