TabContent of the TabSheet has a fixed Pixel Width

Hi all,

I try to include a TybSheet in my Vaadin-Application.
By default the TabSheet has a width of 100% and filles the complete width of the container.

My problem now is, that when I resize the Browser-Window the v-tabsheet-content has a fix width in Pixel.
its parent, the v-tabsheet-tabcontainer has a width: 100%

If i change the tab and come back it is recalculated correctly.

anyone an Idea on how i can change this behaviour?
