Ensures that the layout looks better and doesn't get out of place in the smallest windows and largest fonts, as well as in both English and Chinese environments.

This always increases the bottom height. In fact, I hope to avoid scroll bars as much as possible. We may consider automatic line wrapping.

This issue seems to have arisen in the last PR: #2188

We may consider automatic line wrapping.

How do we do that? I've tried changing the style many times, but it works worse than it currently does.

LGTM. 🎉

Smaller window and oversize font, use Segoe UI.
If this extreme case is not considered, then this can be merged as soon as possible. 🥰

Some fonts cause scrollbars to persist (e.g. Source Han Serif), and I don't know why, but most other fonts look fine. 🤔

The second issue is still there, and I'm personally pessimistic about it — i.e. it's probably not going to be resolved on our end. I don't know what your views are on this.

This is reasonable, all we need to do is prevent the UI from being accidentally cut off.
