how to config IdeaVIM stay in insert-mode after select text mouse move

[liango2]

I'd love IdeaVIM to stay in insert-mode until I leave it via ESC and never switch to normal or visual mode automatically; i.e. if I mark text with schift+cursor(SELECT Mode) (which works fine) and move the cursor afterwards it switches to NORMAL mode and not to INSERT MODE.

.ideavimrc:

set selectmode=mouse
