Yes! I was reloading BaseFocusScript. Oops.
In detail: script files are dynamically loaded when first requested and can be
reloaded for debugging. I think that's safe because script files are
self-contained (e.g. the classes in them are never subclassed or anything like
that). But I went too far: I had my focus scripts reload BaseFocusScript, which
is shared code, so that I could tweak BaseFocusScript while debugging focus
scripts.
Thank you very much!
