Forth column is cut on mildly thin defx window

[oblitum]

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

Forth column ("type") overflows on thin winwidth (happens on small screens, 1366x768 old laptop -> winwidth' : &columns / 4, see minimal init bellow).

Expected

Seems to happen because "type" is aligned to right, but seems to respect some minimal offset.
