Prevent empty title

[Stargateur]

https://mods.factorio.com/mod/heart-attack/discussion have a thread with an empty title it's impossible to click on it

Thus it possible to get it reading the html https://mods.factorio.com/mod/heart-att ... a9914f6201

[Yess]

The title of the linked thread isn't actually empty, it just isn't visible because it consists of two spaces.

It is still clickable (image shows the title with cursor hovered over it):

I'm not saying this as though this is perfectly fine, it is still a silly title that should probably have some kind of validation check to prevent it (just prevent title from being only made up of spaces); just mentioning that the title is technically not empty and is accessible normally without needing to open the HTML.

firefox doesn't show anything and is mostly right to do so "<a href="/mod/heart-attack/discussion/6749ea4542705fa9914f6201" title="ㅤ">ㅤ</a>". title IS empty.

Yes need more than just empty, some rules could help here like minimum length title. at least few non white space character.

Oh! I didn't realise that Firefox does things differently. It seems like Chromium-based browsers display this title as it is, while Firefox turns the title into a null string that cannot be displayed. Also just noticed that this isn't actually a normal space (U+0020), it is U+3164. Probably explains why Chromium doesn't recognise it as whitespace to trim it while Firefox does.
