I would guess so as "ancestor" listener is to support notification when
changes occur to a JComponent or one of its ancestors.

Does it handle the case where the graphics configuration is later changed?

It seems for JLabel, Component.updateGraphicsData() with proper

JTextComponent or JDialog. Do you know why? Because of this,
correct FRC is not created.
I am not sure what else I can do to create correct FRC.
But at some point we will get a correct GraphicsConfiguraiton for a
component, right? It should be called for the window and child when
we show the window on the screen, when we move the window to
another screen, etc.
Yes, it seems to be called when JLabel is added to JFrame but not
before.
Span is calculated in GlyphPainter1.getSpan() which is called when
JLabel is created and
as it seems, not when JLabel is added to JFrame (which is when we
get the correct graphics configuration and therefore correct transform).
So, we need to make sure spans are recalculated when the JLabel is
added to frame, which is what modified webrev does by calling
JLabel.updateUI()

Modified webrev to only update html renderer when JLabel is added to
frame by listening to property "ancestor" which implies component is
added/made visible, at which point correct graphics configuration is set.
