YouTube tabs get erroneously discarded with a not-yet-submitted comment on the tab.

[EricTheDad]

I have the Do not discard a tab when form changes are not yet submitted option set, but I frequently, albeit not consistently, have tabs where I'm working on a YouTube comment get discarded, losing my entire comment in the process, when I open a new tab to look up a definition or double check a fact related to the comment I'm writing.

Possible key circumstances:

• I tend to have a lot of YouTube tabs open at the same time. My primary reason for using Auto Tab Discard is so I can use tabs as temporary bookmarks for videos I want to watch in the near future.
• I don't think the erroneous tab discard has ever happened on the first time I've opened another tab along side a tab with an unsubmitted comment. It takes a few cycles of opening a new tab, using it, then closing it to return to the comment before the tab with the comment is erroneously discarded.

I'll update this issue if I manage to find consistent repro steps.
