Underline highlights in passage/code editor sometimes get "stuck"
The underline highlights (not sure what they're called) in the passage editor sometimes get stuck and won't go away or will act glitchy until the the passage window is closed, maximized, or minimized.
One instance where this happens consistently is with errors at the end of a line.
Steps to reproduce:
Step 2: Add an error at the end of a line.
Step 3: Delete the erroneous text, then move the cursor somewhere else.
