Doesn't automatically set focus on messagebox and makes parent window unusable.

[16Integer]

Hi, I am using this module and have conducted some tests in my code to figure out what could be causing the issue. I have figured out that when using a customtkinter TopLevel window, with no master in the arguements, this messagebox works fine by making the parent window unusable using grab_set and grab_pull, however if using a regular window or a toplevel with a master window specified in my main script, this is not the case. Please help me out here.
