I've added the waiting label here because I cannot reproduce this issue on my setup. I will add instructions on how to test pdf-tools under Vanilla Emacs so that you can try that out and see if the bug persists.

In the meantime, if you know how to install packages on Vanilla Emacs, please test the behaviour and let me know as well!
