I noticed this problem with sub boards where words are written from right to left which are Arabic and Hebrew sub boards.
The problem appears when using Chrome both on computer and smartphone and it works fine using Firefox (I don't know about other browsers).
I also noticed that when I minimize the browser window size, the links become clickable!
I don't know if there is something to do to fix it, I just wanted to let you know about it.
I tested this with
Waterfox (Firefox based) and it works fine. You have probably found a
Chromium bug, which probably affects all Chromium based browsers (Ie: Opera, Brave, Edge, etc).
Perhaps the right course of action is to fill a
bug report to the Chromium development team. I wouldn't be surprised if this happens in other forums, try checking elsewhere (ie.
Simple Machine Forums in Arabic). There is a chance the bug isn't even Chromium but SMF related. You should also test a different forum software, such as a phpbb forum in Arabic to see if the problem repeats. Then you will know which team to send the report to.
