Set fixed size in px/rem?

I noticed that with a splitter that scales to the browser window, my fixed pane was still changing size. How can I fix this to an absolute value rather than a percentage?

Unfortunately we do not support px/rem sizing. It is not trivial. So for now, you will need to calculate it. Hook the pane resize event, figure the pane % based on window pixel sizing and set the pane size

If I recall there is a PR for an formal implementaiton, you want to pick it up.
