Describe the bug

When a user has a directory that has been deleted, the ui flickers before putting the user to the original directory where the forward/backward shift was issued from. this leaves the user in a stuck state as they no longer go back/forward the backstack as they're blocked by the now not-existing directory

Minimal reproducer

create a directory structure like:
testing/
├── dir_1
│ ├── subdir_1
│ ├── subdir_2
│ └── subdir_3
└── dir_2
├── subdir_1
├── subdir_2
└── subdir_3
walk the tree by visiting all subdirs in dir_1 then all subdirs in dir_2 so that all subdirs are in the Backstack. Using "back" ( by default) move to dir_2/subdir_1 so that we move in the backstack stack. open a new tab and delete dir_1/subdir_2 (you can move freely, not only using "back"). Return to the original tab and attempt to visit subdir_1 by only using "back." It will get stuck on subdir_3 and refuse to continue further because subdir_2 that's in the stack doesn't exist anymore

Anything else?

No response

Checklist

• I tried the latest nightly build, and the issue is still reproducible
• I updated the environment information (ya env) field to the nightly that I tried
• I can reproduce it after disabling all custom configs/plugins (mv ~/.config/yazi ~/.config/yazi-backup)
