Screen named as "Label" does not load

I was trying to …
create a screen called “Label” based on an entity called Label
I was expecting …
the screen to load as any other screen with data on the Flash client
Instead I’ve got …
a blank screen.

When screen name was changed to “Label_” it loaded the screen with data.

Fixed in the latest master and 2016.3 versions.

The problem was caused by naming a screen section by a name of an existing Widget.
