fix(url-sync): reverting back to using `change` event (#2183)
fix(url-sync): reverting back to using `change` event (#2183)

This reverts the behaviour of the URL sync to using the `change` event.
Unfortunately it reverts back the state prior to fixing #2105. However
this behavior was introduced on purpose with #1015

Fixes #2173 #2171
