My investigation so far shows that the issue also happens without using xepersian/bidi packages. Look particularly at pages 4, 6, 8, and 10.

Could you please also post Vahid Damanafshan's example from Telegram? I do not have access to Telegram as I left my phone in home back in Australia.

[bahman-mirzakhani]

When I asked Mr. DamanAfshan, he said that I had the same problem.

[kvafa]

I think the two issues are slightly different although somehow related; from memory, I think his example had the old footnote cs \paragraphfootnotes or something similar while your example uses the new footnote cs \ParagraphFootnotes.

Anyway, it helps me a lot if I also can have access to Vahid's specific example.

I asked this question about different methods of resetting footnote numbers for more details. Only one of the methods worked correctly (with footmisc package). Comment: The ones I mark not ok can not work as the footnotes have been allocated numbers before page breaking. That is why footmisc offers code to implement this.

I do not think that it is footmisc that implements it as it loads perpage package. That is, if you load perpage directly instead footmisc, you should also get the correct output.

You are right. Is it possible the bidi package to use some codes like perpage package for solving this issue?

Note: unfortunately the perpage package also transfers the last line of the previous page to the next page and its place remains empty. Even the \flushbottom command doesn't fill it.

I have not investigated the issue thoroughly; I just made some observation without actually looking at what is going on exactly.

One way to go forward is to see what perpage does that 'bidi-perpagedoes not and extendbidi-perpage' to get the correct behavior.

Another possible solution is to avoid resetting footnotes by using a different algorithm.

I just need to find some free time to investigate this and fix it.

[saeidm23]

Is there any solution for the bug?

According to comments, you can use perpage package as follows:

\usepackage{perpage} 
\MakePerPage{footnote}

Many thanks. But that does not resolve the issue.
