Created attachment 469519 [details] A screencast of the bleeding over the edges of the max-height div Steps to reproduce: - Visit the test case at https://jsfiddle.net/e7os0xpu/ I'm running Webkit via Playwright on Linux, and this fiddle causes the message div's to bleed over out of the `max-height` and `scroll` restrictions on the `.conversation` div, as shown in the attached screencast. The problem becomes especially egregious after a bit of scrolling. The command I'm using is npx playwright open -b webkit https://jsfiddle.net/e7os0xpu/ It works fine for me on Firefox and Chrome. I would try to run this example on the latest build as directed, but it appears the contents of main.zip don't support running on Linux. Webkit version: it says 17.4 when I log `browser.version()` on Playwright OS: Linux Mint 21.2
Created attachment 469520 [details] A screencast of how it renders on Firefox This is how it renders on Firefox, which respects the max-height of the container div at all times.
I cannot reproduce this in Safari.
I can't reproduce on Safari Version 17.4 (19618.1.11) on macOS 14.
