[BUG] Memory leak with hidden/extendToSubtree changes

[dreistromlandMf]

Describe the bug

Various changes to hidden and extendToSubtree will cause all child pages to be queued for updating.

In the process of queuing, a TSFE is being built and cached for each page added to the queue. This TSFE exceeds an average of over a megabyte per cached entry in our site, so with a sufficient amount of pages this will consume considerable amounts of memory and possibly die by exceeding memory limits.

To Reproduce
Steps to reproduce the behavior:

1. Create a page with a large amount of (recursive) children.
2. Switch the hidden flag off with extendToSubtree enabled.
3. Observe high memory consumption

Expected behavior
Changing those page properties does not cause excessive memory usage.
