Tree Tile stays blocked forever for other teams after infantry passes through

[CCCP84]

Description

I discovered a very annoying bug: infantry can move through trees right on the cell where the tree is. When the infantry of a specific team passes through the tile where the tree is, this cell remains passable for that team. But for other teams, this cell closes and becomes impassable. Moreover, even after the tree is destroyed, this empty tile remains impassable for the infantry of all other teams forever.
Of course, this can be used somewhere (I passed and closed the door behind me), but this is a serious bug that requires fixing.

I made a map where it is convenient to test this:

So that you understand the seriousness of the Bug, I'm describing a situation: let's say there's a densely forested area, one Unit of one of the teams passes through this forest, and no infantry of any other team will ever cross this line.
