Subject: [PATCH] fix: panicked at 'attempt to subtract with overflow'
helix-term/src/ui/editor.rs:275:29 This would happen when the window-size was
to small to display the entire width and one would start jumping forwards
with f<some_char> and the beginning of the highlighted area would end up
outside of the window
