If the new parentNode gets a `textContent` or `innerHTML` property during patching, the `transition` node would have been detached early, which means `el.parentNode` no longer exists.

Fix #8199
If the new parentNode gets a
textContentorinnerHTMLproperty during patching, thetransitionnode would have been detached early, which meansel.parentNodeno longer exists.So this existential check is necessary.
This is an imperfect fix because while errors are suppressed, transition animations still get lost.
It is due to the different mechanism of
v-htmland VDOM element patching. But fixing that would be much more complex and I don't think we'd bother fixing such an edge case.What kind of change does this PR introduce? (check at least one)
