A detailed description - TextBoxes’ InputBegan events do not fire for MouseButton1 unless the user quickly repeatedly quickly clicks it. This should fire regardless of how many times the user clicks it.
Where it happens - This happens both in Studio and in-game.
When it happens - I first experienced it around May 28th, at 5:00 AM AST
Videos and images - The frame on the right turns black when my mouse button is down (UserInputService), but note that when I click one time, “Input began” with UserInputType.MouseButton1 does not print.
Reproduction Steps
This will reproduce the issue 100% of the time:
1- Create a TextBox.InputBegan listener.
2- Observe the event does not fire unless you repeatedly quickly click the text box.
