Subject: fix: on-screen-keyboard hides on input blur in webview

Changes introduced by this patch fix issue where OSK does not hide on
input rendered inside webview is blurred. This patch should be removed
when proper fix in chromium repo is available.

Note: the issue still occurs if input rendered in webview blurred due
to touch outside of webview. It is caused by webview implementation
details. Specificaly due to webview has its own tree nodes and focused
node does not change in this case.
