ApplicationConfiguration.AlwaysUsePreviewRefresh

Determines whether the Preview browser always does a full page refresh when the preview is updated.

This can result in the preview being slower, more janky and potentially not syncing correctly all the time.

Normally MM tries to do partial content injection of the changed content only, which is must faster than full page reload. However, if you have scripts in the page header or footer these scripts won't refresh unless you handle the previewUpdated event fired on refresh.
