1604559 - Find does not find all instances when instances overlap

Status: NEW

(Toolkit :: Find Toolbar, defect)

Description

[David Heiberg [:dheiberg]]

When searching for a string on a page, it sometimes does not find all the instances. I have tested this on 71 and 73.0a1 (2019-12-17) (64-bit) on MacOSX, also tried with new profiles.

Steps to Reproduce:
1 - Open https://pastebin.com/raw/ady20uBn
2 - Open find with cmd+f or OS equivalent
3 - Enter ,438, into the search field.
4 - Select next till you get to the 4th match
5 - The next item reloops back to the 1st match, despite there being a 5th match.

The issue seems to be with the fact that ,438, is repeated right after itself, and the second match would be part of the original match, like so: ,438,438,. I think this theory is reinforced by the fact that if you were to iterate over the results the other way round (ie "Find the previous occurence") then the second half of the string matches and not the first.
