Unsaved changes message appears after 3 mins whilst still updating

[jobiddulph]

I find this pretty intrusive when I'm updating, after 3 minutes of updating an article, I get the 'You have unsaved changes Discard them?' message, so I then have to save my content or discard it. I don't want to be asked this message unless I have navigated away from the article and I am returning.

To reproduce, create a new article and start updating a lengthy piece of body copy, after around 3 minutes you should see the unsaved changes message

Publish v.3.0.0

Discussed with @eduardoboucas; I can't reproduce this in any way 😕
