Description john-ivan 2020-10-06 08:45:30 PDT

SYSTEM:  Debian Buster x86_64
BROWSER: Epiphany 3.32.1.2
WEBKIT:  WebKitGTK+ 2.28.4

REPLICATION:
1. Go to https://yltbible.site/study/tool.html
2. Click 'A-piece to Angle'
3. Click 'A-piece to Abhor'
4. Click 'A-piece'
5. In top-right frame, click 'Numbers 3:47'

PROBLEM:
The proper result(as in Firefox78.3.0esr) is to go to the internal link at Numbers 3:47.
WebKit seems to be not realizing that the iframe only has 49.5% of the screen height;
it seems to be rendering as if the iframe has 100% height but is covered.

I can reproduce in Safari, it scrolls to the wrong position.

This is about multicol. The "columns: 2" triggers it.
