Changing properties then pressing F5

I found the following bug:

  1. Change a property of any object by typing numbers. For example size of a part or value of a variable object.
  2. Instead of pressing Enter, immadiately press F5 to test the game with the new values.

Roblox Studio seems to apply the new value (the value looks like set to the typed one, not reverted back to the original ones) but actually it still uses the previous value.

Entered value will be applied after stopping the game and hitting F5 again.
