Label does not resize on splitter

Hi,

i attached some different controls (text box, picture) to a vertical splitter. The attachment mode is "splitter sizes control".

When i resize the panel, the control is sized as expected, but the label of the controls are not resized. 

F.e. if the original width is 300 points and the new width of the control is 500 points, the label still has a widt of 300 points.

I know, that i can do a workaround a resize the label by myself in code, but i think it's a bug on splitter behavior?
