find does not produce the desired output.
When I write some text in the find search bar, the text being selected in the editor is wrong.
The selection boxes with a colored border or background appear in the wrong places.
looks like you have a non-monospace font.
Which OS/Browser is this?
Have you changed the font intentionally, or is it the default?
I wanted to try Firacode. Browser is Chrome, OS is Windows.
