How to clear `Undo` history after closing file in JetBrains WebStorm or PhpStorm or other jetbrains products?

Is it possible to clear undo history after file closing? Or in the other words:
How can i disable Undo After File Closed?

It is a little bit confusing, when you open file, do something and after that you want to rollback, you hold Ctrl+Z and implicitly rollback all changes including previous closed file usage changes.

to reproduce:

open file
write A
close file
open same file
write B after A
press and hold Ctrl+Z

you will see that both changes are gone and this is not a good feature, To me, this risks unintended/accidental changes.

Is there any option to enable/disable this functionality?
