This happens when merging PRs https://github.com/aio-libs/aiohttp/pull/4731 and editing individual files https://github.com/scop/aiohttp/edit/changelog-project-url/setup.py?pr=%2Faio-libs%2Faiohttp%2Fpull%2F4731.

Looks like it’s because of

.rgh-monospace-textareas #merge_title_field, .rgh-monospace-textareas #commit-summary-input {
    width: calc(72ch + 18px);
    max-width: 100%;
}

Can it be that ch counts the char width as 0 if an incorrect font is chosen?

Likely. Perhaps also try replacing the font-family to just monospace

Anyway this sounds like a system or browser problem not working correctly rather than Refined GitHub’s.

We can’t use the em unit either because it seems substantially different (72ch ≅ 43em on my system)

max-width: none doesn’t change anything. width: calc(72em + 18px) fixes it.
