the project's righ click menu height changed after load finished

plz check the video I upload.

When project finished the loading ,the menu heightened one entry's height ,

Which will make the mouse click the wrong menu.

I want to close `all other projects except this project` ,but when I click as the menu abruptly 

have an extra entry called `run ` .  Though my mouse has not changed ,  the clicked item has became

`close the current project`.   Which is againt my intention.
