I'm currently completely rewriting an old MX Flex application, porting it to Spark, it's mostly finished, but I've noticed an error. I have some Labels with showTruncationTip to true, but when the label is too small to display all text and it's truncated, the tooltip displayed is just a small yellow rect completely blank.
I've tried both Flex 4.12 and 4.14, and the behaviour is the same on both versions, am I doing something wrong or is this a bug?
