[Bug] Can't blur filter textbox (input)

[WietseWind]

When filtering events, you type something, the events are filtered. So far so good.

Now (by tapping outside of the filter textbox (input)) the keyboard will still be displayed, focus still in the filter search input. This limits the amount of screen space available to review the found transactions. Look eg. at Bunq: to apply (text) filter, one has to press the "search" button @ keyboard, then the input blurs, keyboard goes away and filter starts.
