What happened?:
when typing arabic numbers two problems can be noticed.

first, a normal empty page, number becomes 000'06 instead of 60'000

when typing as you write, from right to left, numbers are printed the wrong way, no matter if arabic thousands separator, U+066C), is used or not.

steps to reproduce:

1. go to arabic wikipedia, create an empty page
2. use google translate to translate a sentence into arabic, incouding a number
3. paste it into the empty page. play with the number. replace the thousands separator with an arabic thousands separator from https://www.compart.com/en/unicode/U+066C, or a single quote (apostrophe). or type the whole number with these thousands separators.

second, in templates, number becomes 000'60

second, a template, e.g. on https://ur.wikipedia.org/w/index.php?title=%D8%A7%D8%AA%D8%AD%D8%A7%D8%AF_%DA%A9%D9%84%D8%A8_(%D8%AC%D8%AF%DB%81)&action=edit

typing 60'000 with quote becomes 000'60. typing 60'000 with arabic thousands separator is correct: 60'000. see attached screenshots. typing it from right to left does not work, for both numbers and text.

steps to reproduce:

1. open url https://ur.wikipedia.org/w/index.php?title=%D8%A7%D8%AA%D8%AD%D8%A7%D8%AF_%DA%A9%D9%84%D8%A8_(%D8%AC%D8%AF%DB%81)&action=edit
2. search for number with thousands, insert the different formats with different thousands separators.
3. exit template edit and see error, do not save the page.

What should have happened instead?:
in all cases the number should be 60'000.
