Tab Overflow

I have several windows with tabs filling up and overflowing the tab bar.  On most windows the far right tab is selected.  After restoring a session, *all* of my windows whose tab rows are full and that have the rightmost tab selected are scrolled ever so slightly off the tab bar - the bottom curve it seems (see attached screenshot).
I tried reproducing this with a different profile (filling several windows with tabs) and ironically could only get the *leftmost* selected tab to trail off the end, like the screenshot, on session restore.

It's obviously not a showstopper, but it's poor polish and for someone like me with that tinge of OCD I have to go through and hit the scroll arrow on all the cases. It just looks bad.

Hm, I could reproduce this last week but can't anymore. Caspy7, can you still reproduce this on a new nightly build?

Still seeing this on the latest nightly.

Ok, I can reproduce with the left-most selected tab.
I'm pretty sure I've gotten it figured out now. Patch coming soon.

Kinda stinks to reach in to private methods and properties of mTabstrip, but it's not the first place within tabbrowser.xml.

Patch v1.01 (forgot to qref)

I agree on both the gross-ness of sucking out private members of mTabstrip, and also at the sentiment that "we were doing it already, so what the hell."

We really should consider trying to expose those as public read-only members instead. I wouldn't block on it, but can you please file a bug to do that?

Also, have you done a try push to see how this could affect TART? If not, maybe do that. Or not, and take your chances on fx-team / m-c. :)
