[schwas3]

Steps to reproduce:

Open a file in VSCode using rfv Open a histogram or other grahpic Use the Enlarge canvas option on the bottom left options Before enlarging: After enlarging:

On the left, the TBrowser navigator (for lack of a better term) can still be seen behind the canvas, as if the canvas has some kind of transparency setting.

I can see this also happening when JSROOT is running standalone (see https://jsroot.gsi.de/latest/api.htm#custom_html_file_browser,) so maybe this is the intended behaviour. CCing @linev so he can tell us.

Yes, it is intended. Enlarged canvas is by 10% transparent
