[BUG] No filtered pagination in backend module

[ErHaWeb]

In the “Mail” backend module of powermail v12.5.0, filter values are currently lost when jumping to other pages via pagination. As a partial aspect of the problem I could already determine that the JavaScript, which assigns the pagination links with a click event listener, still uses the old class name .pagination instead of ._pagination.

If the class name is corrected in the relevant JavaScript EXT:powermail/Resources/Public/JavaScript/Powermail/Backend.min.js, I currently get the error that the value from tx_powermail_web_powermailm1[currentPage] is no longer evaluated and the selected page is not jumped to.

Further debugging has not been possible for me so far, as I have not been able to successfully start the JavaScript build process due to npm version conflicts.
