Splitterposition not setable after user drag

Hi!

The splitLaout alows for programatically setting the splitterposition with setSplitterPosition(), but it seems like this is disabled when position is changed by user. Afterwards the setSplitterPosition() has no effect. Is this intentional? Is there some way to aoid it?

Sounds like this bug: https://github.com/vaadin/vaadin-split-layout-flow/issues/47
