This is a minor bug
When the option below is set:
selectionModel: { type:"row", mode:"single", column:false, all:false, toggle:false},
when you touch and move away from a row (like slide or roll your finger on the screen) but not select the row, the hover highlight stays on the row (see attached image) so eventually you end up with lots of rows highlighted. This is the same on iPhone and Android.
