+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.
