PR summary

Ticks will follow thercParams at the time of their creation, if there were no other settings used. If thercParams are set in a context, then the lazily-generated ticks may start fetching the wrong values. This is fixed viaAxis._copy_tick_props by copying the properties from theTick's childArtist's to the new ones. However, internal attributes fromTick are not copied, which is generally fine for drawing because nothing is every re-synced from there.

However, in the case ofSpine's window extent, it is generated from the tick direction and size attributes on theTick, so being out of sync may cause an incorrect bounding box if the tick direction changes. SinceSpine chooses a randomTick, this will cause tight/constrained layout to be nondeterministic.

Since this is nondeterministic, I'm debating how best to write a test.

Fixes#28574.
