Steps to reproduce
Create an SvgPicture with a semanticsLabel, but no directionality?
I'm only creating this issue because the stacktrace suggested it, and I couldn't find any existing issues related to this.
Expected results
Expected not to get a stacktrace in the console
Actual results
Got an exception.
