incorrect highlight

[t9md]

I think this is caused by upstream issue(https://github.com/atom/atom/issues/15581).

e.g narrow:search, this.vimState.occurrenceManager in vim-mode-plus codebase.

happens regardless of searcher(ag, rg).

This is because of odd cursor column measurement on TextEditorComponent.

• When cursor is mode in onDidChangeActivePaneItem
• And measureHorizontalPositionsOnLine() was called on not visible editor's component.
• This result in caching incorrect measurement and used when it's become visible.

But anyway, I'm also finding the way to solve this bug in client-side(=narrow pkg).

#286 might fix this issue. If I won't see this issue for a week, I'll close. Then reopen when I hit it again by any chance.
