[FIX] website: ensure order of we-matrix's events

This commit ensures that changes are applied in the same order as the
events are triggered on the we-matrix. This was not the case because of
another bug we had to consider and which is not there anymore, this is
why this fix is done in 15.0 and not before.

This commit is the continuation of [1] which applied the same change for
we-input.
