Editor tabs getting locked

Hi,

is there any reason why the editor tabs/preview tabs are locked by default?
I have this weird bug(mostly for Flutter projects) where I go to a preview tab I see it’s locked and I go to a code file when I come back to the preview tab it’s again locked.

This is an issue because no matter how many times I unlock it it keeps locking back and when I open a new file/create a new file it splits it to the right

Is anyone else facing this issue? Is there any way to disable locking? or any workaround??

Does anyone have any solution… :smiley:
changing below settings also don’t seem to help
