Description

Activating vaadin-multi-select-combo-box clear button with touch clears <input> value, but not filter property.

I was able to reproduce this in Android Chrome, iOS Simulator and in the Chrome devtools device emulator.

Expected outcome

Expected either the filter to stay preserved (as on the desktop browsers) or to be removed.

1. Open the dev page in this repo in Chrome
2. Enter the device emulation mode in console
3. Open the MSCB dropdown, type something
