Keyboard navigation in the Log tab is kind of messed up by the "watermark"s

[EmJayGee]

I believe this is caused by the "watermark" reading "Properties and items are available at evaluation ..."

If the node that's highlit here has focus and you use the down arrow to try to navigate down the tree view, selection disappears.

Perhaps this is because that yellowish box can gain focus?

Theory somewhat corroborated by the fact that up-arrowing from below also sees the current node go into a black hole.

This is probably WPF and I know very very little about silverlight / wpf UI. "Back in the day" there were properties about selectability vs. disabled and maybe there's something like that here?
