fix: touchscreen interactions don't require extra presses

previously activating a control meant tapping it once to enable
proximity, then tapping it again to do the actual interaction.
now a single tap will do that.

previously the following glitch was present:
- interact with a slider
- release touch on that slider
- touch a different control
->input would be received by the old control

now the input is received by the correct control
