It's not a big problem to customize it in terms of RTL; however, I have no idea how that would effect the English version, which is the core of this system. I guess it's better to fix it by myself since I don't care how that would affect the English version.Issues like these are generally nightmarish (if possible) to fix. It has to do with "affinity" for RTL vs LTR and how the browser then lays text out. It is very dependent on the particular text in question - if you use an actual RTL character there, you can see the change. This is entirely down to browser (well, Unicode) layout rules.
I think this is related to the same issue, but this one is more critical since it makes no sense to the reader:No, one thread per bug is always better.
