Problem
While hydrating custom elements, set_attributes temporarily disables global hydration state via set_hydrating(false) and restores it only at the end. If a prop setter or attribute operation throws partway through, hydration mode can remain disabled globally.
Fix
Wrap the temporary hydration-state override in a try/finally block in set_attributes so set_hydrating(true) always runs when is_hydrating_custom_element is true.
Validation
No runtime tests were run in this PR workflow. This is a control-flow safety fix to ensure state restoration under error conditions.
