If I click the cursor on the topic name and edit it, but it turns out to be too long and an error message appears. And then everything just gets erased! This is a very bad interface and needs to be fixed.

The limit for the field is 255 characters.

I tested this, and if I make the title too long, I do see the error popup, but the title is not erased, it retains the previous title.

Are you able to reproduce this with all 3rd-party apps, plugins, and Themes, disabled?

Yes, that's right!

The old header remains, and the new corrected one is lost.

Yes, that's right! The old header remains, and the new corrected one is lost. Why can't I give the option to edit further after the error window?

If I've understood what you mean, you can edit further.

As soon as you dismiss the error popup after exceeding 255 characters, you can click/hold the title and edit again.

But it doesn't retain the edit which is too long, it only retains the previously saved edit. That part is working as intended (or at least, as written).

Yes! A warning that I exceed the length should appear near the input field during editing. So that the work done is not wasted, because it infuriates!

Bad idea  🙂
