Description

I came across a crash while hovering over a number of items that have powertips. This is some sort of open/close race condition, because it doesn't happen often, although I can reproduce it somewhat easily.

The error message is: Cannot read properties of null (reading 'data')

The image below illustrates the moment of the crash, the tip is open, but there is no active hover. Can it simply be fixed by changing:

				if (!session.isClosing) {
					hideTip(session.activeHover);
				}

to

				if (!session.isClosing && session.activeHover) {
					hideTip(session.activeHover);
				}

Using version 1.3.2
