lock the cursor on its current highlighted file when we toggle hidden/ignored files (pressing H or I)

Is your feature request related to a problem? Please describe.
When we toggle hidden/ignored files by pressing H or I, the cursor stick to its current line rather than the current file

Describe the solution you'd like
It's a good idea that the cursor sticks to the file it's on rather than the line

Describe alternatives you've considered
NERDTree is a good example, when we press "I" to toggle the hidden files the cursor sticks to the currently highlighted file
