Steps to reproduce the problem:
1. Find the id of a touch device with xinput (In my case, "Wacom Co.,Ltd. Pen and multitouch sensor Finger touch" has id=9)
2. Launch the browser with  `google-chrome --touch-devices=9`
3. Touch input in Chrome works as expected
4. Disable another xinput device, for example by `xinput disable "TPPS/2 IBM TrackPoint"`
5. Touch input in Chrome no longer works
6. Enable the other device again with `xinput enable "TPPS/2 IBM TrackPoint"`
7. Touch input in Chrome still doesn't work

What is the expected behavior?
Touch should keep working when I disable/enable other devices.

What went wrong?
Touch no longer works after disabling another device with xinput

Did this work before? N/A

This is particularly annoying on convertibles, where I would like to disable my touch-pad when folding to tablet mode, but this then also kills touch input in Chrome.
