Build is 1.7.552.0.

  • run wt ; nt
  • mark the second pane as read only

On the debug build, I wasn't able to get them to appear, until I stepped through it once, and now they always appear. Like, no launches of the terminal ever had them, now all launches of the terminal have them

When I was first debugging through this, it looked like PaletteItemTemplateSelector::_TabItemTemplate was null. However when debugging the release build that doesn't repro this, _TabItemTemplate definitely isn't null, so that can't be it.
