I had a look on this tonight. I am pretty sure you accidently acitvated OSGB36 projection. If you activate the showing of the lat/lon Grid you can see that it is not parallel to the X/Y Axis. The bounding box of a relation is currently calculated using the lat/lon coordinates. Now when pointing the box around the relation, 2 oposed nodes of the bounding box are projected and from these the box to draw is retrieved. Unfortunately when calculating the box for the Snap event, the other 2 oposed nodes of the bounding box are used. In case that the lat/lon grid is not parallel, this box will not be the same. So to hover and focus a relation, you must find an invisible box. I started a merge request for a hotfix to calculate the snap box in the same way than the drawn box. Since I am not really happy with this solution, I will think about an easy way for better bounding box calculation.
