Why does watermark have z-index: 1 ?

[StefanH-AT]

I see that .dv-dockview .dv-watermark-container has a z-index: 1, which breaks some overlays I have in my app. I could hack everything else to have a higher z-index of course, but it seems strange that dockview even sets a z-index for watermarks and only watermarks. Actual panels don't get one

My guess is this was added because of the adjacent .dv-branch-node sibling that comes right after it? That branch node is an empty div that takes up full width and height and blocks user input

But can't we just remove that branch node?

This CSS rule fixes the issue for me. The branch node div does nothing but block input.

.dv-dockview .dv-watermark-container {
    z-index: auto;

    + .dv-branch-node {
        display: none;
    }
}

Or does it? Is there a reason for it to be set up this way?
Thanks
