[Bug 534606] [NEW] Find positions match off-screen

[jimav]

Public bug reported:

Binary package hint: firefox

When using the "Find" feature (Control-F), matched text is frequently
invisible, presumably positioned outside the viewable portion of the
page.   Perhaps the line containing the text is slightly (e.g. one
pixel) on-screen, I don't know; in any case, the match is completely
invisible to the user.   It might depend on the font sizes being used.
(just guesses).

Here is a demo of the problem:

1. Go to https://investing.schwab.com/secure/cc/guidance/taxes/tax_forms/1099_composite?cmsid=P-2181822&lvl1=guidance&lvl2=taxes
(you might need to have a schwab account to see it, not sure).

2. Make the window wider than that text, but only tall enough for three
lines of text; scroll so that the top visible line is the line which
begins with "Form Highlights".

3. Control-F and type "K-1" into the Find: field, without the quotes, and hit Return.
    Firefox auto-scrolls to some other position, but no K-1 is visible anywhere.
4. Click 'Next' several times.  Firefox will sometimes show a matched K-1 in the text, sometimes not.


Please look at the attached screen shot showing a "match" which is invisible.
