Comment (by cypherpunks):

 > 5. In the first tab, open the browser's Find box (Ctrl+F) as if you were
 searching for text on that page. Notice the vertical size of its
 letterboxed page area shrink as it's supposed to.

 I should have said, "shrink as ''I guess'' it's supposed to," because I
 don't know if it's supposed to shrink the page area or if it's supposed to
 overlay on top of it.

 I found more issues that appear to depend on previous steps and may be
 related to Bugzilla's 1593585 (part 2):

 0. Have multiple tabs opened to other pages.
 Next, do the steps in the description, paying careful attention not to
 hover your mouse cursor over the other inactive tabs.
 9. While viewing the second tab (the one ''without'' the Find bar), slowly
 move your mouse cursor over the other tabs in the tab bar. When the mouse
 cursor touches a particular inactive tab, the page area of the tab you're
 viewing will spontaneously grow.
 10. Click on the first tab (the one ''with'' the Find bar). Notice it,
 too, has grown.
 11. While viewing the first tab, slowly move your mouse cursor over the
 other tabs in the tab bar. When the mouse cursor touches a particular
 inactive tab, the page area of the tab you're viewing will spontaneously
 ''shrink'' back to its Findbar-letterboxed size.

 I have not been able to reliably reproduce this behavior, and it doesn't
 always result from hovering over the same inactive tab in the tab bar. I
 can sometimes reset the behavior by closing the Find bar and refreshing
 the two experimented tabs.
