1559372 - Find in page doesn’t work for Instagram Following

Status: RESOLVED DUPLICATE of bug 1482147

(Core :: Find Backend, defect, P2)

Description

[aruseni]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

1. Opened Instagram
2. Opened the “Following” list (see screenshots)
3. Tried to find a user using Ctrl + F

Actual results:

I can find the user if they are either displayed or if you scroll further down. If they are below the displayed portion of the scrollable list, they are not found.

Expected results:

I expect any (loaded) text to be found with Ctrl + F. I checked that the element is present in the DOM: you can find the li element for this user if you search for it with the Developer Tools.

Brad Werth,
Your bunch of patch seems to cause the regression. Can you please look into this?

Too late for a fix in 68 but we could still potentially take a patch for 69/70.
Mike, can you assign a priority to this issue? Thanks!

Brad, is this perhaps a known issue already that we can dupe, perhaps?

Very possibly this is Bug 1482147. I'm going to make this blocked by that bug for now, and will re-test when that bug lands to see if this one is a duplicate.

I actually can't reproduce in Instagram, but the description of the problem matches what is going on in Bug 1482147.

I can reproduce. The key is to get the searched-for-text to be within the bounds of the window, but out of view of the scrollable element. This is trivial on Instagram if you bring up the following pop-up, scroll down a bit and note the text there, scroll back up and then search for the target text. It will not be found.

This is further evidence that this is Bug 1482147. I'm marking this bug as a duplicate.
