Esc to close does not work on gmail

[xi]

submitted via email:

I notice that ESC will close the extension in firefox. I am using the bookmarklet in chrome. ESC does not work there. Must refresh page or navigate somewhere. Can ESC be added to the bookmarklet to close it?​

ah... tested again before I sent email. ESC works on the dozen websites I checked, except for GMAIL. must be a google thing.
