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.

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