BindAction should inform that mouse clicks won't over buttons

Isn’t this expected behaviour since most of the time, we don’t want click operations to fire when we click a button such a ‘buy’ etc.

This doesn’t seem like it should have high impact.

It’s not entirely true. A function cannot be defined by something like “most of the time”. Either it is or it isn’t.
UserInputService.InputBegan is activated even when a button is clicked. ContextActionService:BindAction should do the same. Or, if not, there should be a good explanation for this, and more importantly, this limitation should be documented, which doesn’t happen in both cases.
So, once again, let’s let Roblox judge this.

ContextActionService is used for, as the name implies, react to inputs depending on the context of the action. Clicking freely not on a button is obviously a different context than clicking on one, if you want the “always” behavior I recommend using what you yourself already mentioned:

Printing out the mouse input as a string from UserInputService.InputBegan will only print out “Unknown”. This includes right mouse clicks, which means you can’t differentiate between mouse 1 or mouse 2 inputs. I recommend using Mouse.Button1Down / Mouse.Button2Down instead

As people stated above, this is not a bug.
