…nodes when toggling them open, less it looks glitchy and feels unresponsive.

I adjusted this so it sets the class after half a second rather than waiting for you to click it. |

This closes #13457.
The issue was caused by starting transitions firing when disclosures opened, since the tree nodes were "appearing", causing an opacity transition.
This is a simple fix that adds a modifier class to the
.page-treeafter it's been interacted with, so we can effectively disable the initial transitions after anything has been clicked.I would have gone with an HTML class approach for transitions here, but I couldn't easily modify the inner HTML—so this is simpler.
