Revert "Now math previews are correctly updated when replacing math contents inside"

Updating all previews (even if only one has changed) is more costly
than I thought. Thanks to Guillaume for tracking down this
performance issue.

This reversion is related to the reversions at 358745d0 and
a7a14395. See also #7242 and #9855.

This reverts commit 29948eec26ffc90bdfe0b853aa79d30cfa36c08d.
