Right-to-left (RTL) filenames
Currently, RTL filenames display weirdly - the name is jumbled up near the end, while the start is seemingly okay, or vice-versa.
Examining the HTML, it appears the extension split is done improperly, 2 characters before the dot, instead of at it. So the last few characters of a filename without the extension are actually added to the extension span element, which should remain LTR - but now causes everything to jumble up.

Better support for RTL languages (and Hebrew support..) is needed basically everywhere. All major languages are supported already, so I think RTL support and RTL languages (Hebrew, Arabic..) should be prioritized because it's very difficult in a LTR interfaces.

For me the file names just upload in reverse, meaning there's no support for dir="rtl"
