The claude.ai web UI has a bug right now. If you inline some code by typing an opening backtick then the closing backtick swallows your space, puts the next letter you type after the code, then everything else back inside the code span.

One day we might be able to write software without bugs. That day is clearly not here yet.

(Firefox in Linux if anyone wants to repro. Can’t file a bug as it’s a closed, proprietary piece of software.)
