Monospace and Reset Format Behavior

How to Reproduce

1. Create a new page
2. Type: "One, Two and Three"
3. Highlight "Two" and format as monospace.
4. Set cursor in front of "Two" and insert "One and a half, "
   • Issue A: The newly inserted text is monospace, too
5. Mark the inserted monospaced text "One and a half, " and reset format.
   • Issue B: This resets the newly inserted text as well as "Two", to non-monospace
