Go to demo grid page

Click any grid's filter menu which contains text field

The filter menu automatically closed, so you can't enter anything

ADMIN EDIT
this happens because the keyboard pops up, changes the screen size and may even scroll the page, and both of these events hide the popup menu.
A workaround could be using the filter row mode, with the caveat that it takes up more space on the initial rendering, and that filtering happens immediately.
