Description

marktext hangs when navigating certain markdown document with PgUp and PgDown keys

• Can you reproduce the issue?

Steps to reproduce

1. Open marktext
2. Switch to Dark Mode (probably not related, but just to be sure)
3. Save this document somewhere on your drive
4. Open saved file in marktext
5. Scroll to the end of document with mouse and leave cursor there (I mean text editor cursor)
6. Now try to navigate using PgUp/PgDown keys. Marktext will hang after 3-4 times

Expected behavior:

Expected it to work 😸

Actual behavior:

Editor hangs. From the looks of it renderer process catches infinite loop, as it consumes the whole processor core after hanging. Reproduced on both Windows and Linux, if it would be hard to reproduce on your end will gladly provide proof gif.

Versions
