Change scrolling behaviour of 'Next Problem' Fixes #156782

[r3m0t]

See issue #156782

I made the F8 key (next problem) behave as similar as I could manage to Alt+F3 (next change in file) (although I couldn't get the code to match)

To test I just made some one-line changes which introduced problems. Like this ( vscode-extension-samples repo )
