Middle button area too small in touchpad software button
Summary
On a Dell Precision 5480, using "software button areas" to emulate left, middle, right buttons on the touchpad, the locations and sizes of the virtual buttons are wrong. Namely, the middle button is correctly centred but the width of the middle button is ridiculously low (it is about as wide as one finger), while the left and the right button occupy all of the remaining space in the lower area of the touchpad.
This makes it very difficult to press the middle button with any kind of consistency.
Ideally, the left, middle and right button should each occupy a third of the whole space. Or even better, their widths should be made configurable. In any case, their current widths on this particular computer is a problem.
Steps to reproduce
With gnome-tweaks, configure "Mouse click emulation" as "Area". Then try to press the left, middle and right buttons on the touchpad.
