in the nemo window left clicking after right clicking often does nothing

[betteropensource]

In nemo, if I right-click on its window the contextual menu will appear but now if I left click out of it does nothing and the contextual menu remain opened.

Sometimes I need to click also 10 times before it works, sometimes I first need to move the mouse to be able the left click with it opened.

In all others programs, by doing that the contextual menu correctly closes.

I'm using Ubuntu 18.04, just installed.

This bug is still active on Ubuntu 22.04, now the not clickable area is much bigger!

The problem is still present, almost 5 years have already passed, will it be solved? I'm using a fresh Ubuntu 22.04 install...
