Trackpad tap-to-click not working.

[Jenrikku]

Describe the bug
Tap-to-click on a trackpad from a laptop will not respond. You cannot interact with any element by tapping the trackpad.

To Reproduce

1. Make use of a laptop or similar device with a trackpad.
2. Try using the tap function to click on a button or menu item.
3. Nothing should happen.

Expected behavior
The tapping should be usable to interact with the GUI.

Operating System:
Arch Linux, using X11 with KDE Plasma 5.
Seems to also happen on Windows in a different program with a similar ImGuiController (the one mentioned below).

Additional context
The issue is most probably within the ImGuiController as the one that is included in Silk.NET.OpenGL.Extensions.ImGui has this same issue.
