I do not understand how to do all of this.
sorry, but this stuff is not my thing.
It is still broken with the new update that came out.
I create a new option at ver 1.252
please set new option
Dashboard / Appearance / Customize /
Tab Document click
Disable Keyboad Focus value set disable
Click Saved button
then maybe show sub menus.
To try, I want you to tell me the results
If it normally appears, depending on the menu of the operating environment in the next version, automatically adjusted version is created
Thank you.
