It's basically another bug in Tk on macOS using the Cocoa backend. Other applications have no problem handling Shift+Command+H, however Tk's keyboard handling simply listens to key events and doesn't catch/override the NSWindow's default key bindings so the Command+H gets caught by the window and hides it.

Annoying, but I didn't want to wade into fixing Tk at the time in order to achieve cross-platform consistency.

It was changed to "J" because  macOS reserves "cmd-h" for something else.

Nothing to worry, but little confusing:
in 0.49 (and 0.48) the shortcut for the horizintal slider is Shift Control J and not H, as it has been before.


Is this normal ¿
