Steps to reproduce:

• Create/open a project
• Add some image assets to it, in default Images folder
• Collapse/expand Images folder first by clicking repeatedly arrow icon beside Images
• -> works as expected: every click takes effect no matter how quickly you are clicking
• Start collapsing/expanding in turns by clicking Images folder name
• -> If you click slowly enough, it works, but if you do it more quickly, only every other click seems to work.
