This reverts commit 1736bcf4e918f13c78ade1d446c7222c720d4d6a.
> StyledLabel size caching was not really working due to width check
> did not take control insets into account. So any call to
> GetHeightForWidth or Layout caused full layout recalculation.
> When view with StyledLabel is created CalculateAndDoLayout that
> does all layouting job is called for five or six times with same
> arguments. And each call caused StyledLabel reset and controls removal
