Trigger re-measure after updating ElementResizeListeners. (#11912)

Removing ElementResizeListeners from an element makes it unmeasurable
and clears any saved measured values. Adding the listeners back makes
the element measurable again but doesn't add it to measuring queue.
Measuring needs to happen or any updates to expanded components within a
layout (without changes that would trigger full re-measuring of the
layout itself) lead to broken expand size calculations with any fixed
size elements assumed to have no size.

Fixes #10734
