Browser extension froze when trying to decrypt a compressed PDF file with 340+ pages #4547

Description: Our browser extension was normally able to decrypt pdf and other files. However, we received an unusual scenario where the browser extension is unable to decrypt a compressed pdf file with 340+ pages.

In my testing cases, most of the encrypted attachments are getting decrypted without any problem - the problem is only noticeable with zipped pdf files (only pdf files are tested for the moment).

The user won't be able to download the file either so the attachment seems to be inaccessible.

Were you able to reproduce freezing with your own PDF? If yes, could you link an online sample here for testing?

@tomholub Sorry, what I really mean is a zipped pdf file - it makes the browser extension crash and unusable (which can be resolved only by re-enabling it from the chrome://extension or about:addons)

We can use the sample file from the compatibility account: https://mail.google.com/mail/u/flowcrypt.compatibility@gmail.com/#inbox/WhctKKXXPDKqwfXtDPhhzxBlqlfxDtmnhVSNZWGttjkWrHRlbTrNDKQqjfzpSjcQmZCpBXQ

Hi @martgil, I tried to decrypt mentioned message and it worked well for me, can you please re-test it on your side to check if original issue is fixed now.
