TYPO3 Core

This is due to a change in ext-all-notheme.css. See:
https://review.typo3.org/#/c/24883/4/typo3/contrib/extjs/resources/css/ext-all-notheme.css

The pointer was there (and still would be) because of:
.x-tree-node-el {
cursor: pointer;
line-height: 18px;
}

But x-unselectable kicks in now:
.x-unselectable, .x-unselectable * {
...
cursor: default;
}

Vendor-prefixed cursor-definitions for "unselectable" were in place in the past already, just the generic "cursor: default" got added now.

The x-tree-node item remained identical. Only the div got another class added.
Before:
<li class="x-tree-node"><div unselectable="on" class="x-tree-node-el x-tree-node-leaf x-unselectable" ext:tree-node-id="p2" id="extdd-3">
Now:
<li class="x-tree-node"><div unselectable="on" class="x-tree-node-el x-tree-node-leaf x-unselectable x-tree-selected" ext:tree-node-id="p2" id="extdd-3">

Where does the "unselectable" in the tree come from? Is that something we can avoid? Or is it there in our tree on purpose, so we should style this detail in our pagetree with custom-CSS?

Patch set 2 for branch master of project Packages/TYPO3.CMS has been pushed to the review server.
