InitialSizes overrides minSizes

[ChecksumDK]

I have set initialSizes and minSizes and expect the minimum size to 300px, but the minSize is overridden by the initialSizes values.
When I try to move the pane the splitter "jumps" to the correct minSize immediately.

<SplitPane split='vertical' minSizes={300} initialSizes={[1, 4]} > <LeftPane /> <MainPane /> </SplitPane>

I guess its a bug.
