Tree item doesn't contract right after being expanded

[Daniil Shved]

I have attached a screenshot to better explain the situation. On the screenshot you can see a Nautilus window showing my "music" folder. Some of the subfolders are expanded, some are not. The "Instrumental" folder is expanded. In fact, the screenshot shows the situation right after I expanded this subfolder, and the mouse pointer is still over the triangular arrow near the folder icon.

Now, the problems begin when I try to click on the triangular arrow again. What I expect is that the "Instrumental" subfolder will contract, and if I keep on clicking it should expand, then contract again, then expand again, and so on. What happens in reality is nothing: I keep clicking on the triangular arrow, but the subfolder just remains expanded. However, if I move the mouse pointer just a little bit and click on the arrow again - then the folder contracts as expected.
