Lets say you have a 3 pane splitter. All of them have min width. First pane is collapsible. If you collapse first pane, then minimize second to its minimum, and after that you 'uncollapse' first one - it ingores min width of second pane, and just kinda collapse it.
Please have a look at this example:
1. Hide first slider
2. Move the second slider towards the hidden field to its minimum size.
3. Uncollapse the slider from step 1.
Is it normal behavior or it's some kind of bug? If not - how to avoid it?
