thank you for your report! I can replicate all of the points, except point 2, but I guess that one is because of the different LTR language I used. What is the one you have?
To be honest, I don’t know which language I choose, but it seems different than the one you have:
My language is persian. But I don’t think it is different from Arabic. Because both are RTL.
In the second case, if we use the svg icon, the result is worse. Please see this link.
I’ve created an internal task for this bug report, and regarding the second one, I was not able to replicate it to this extent.
I’ve added it to the task anyway, but I may not be able to replicate it.
