When I had a Claude account (cancelled ~May time) I vividly remember the web chat having broken editing for backtick-quoted monospace text. If you typed <space>`foobar`<space> the last space would move the cursor backward into the closing quote, and the space would be emitted inside the monospaced region. It was like this for several months (on Firefox). I always found this baffling for a product marketed to programmers.
