When filter "type:node untagged" the snapping behaviour stops working when joining two nodes

[ggeldenhuis]

What steps will reproduce the problem?

1. Enable the filter type:node untagged
2. Create a square and click slightly off the 1st node
3. A 5th node is created rather than a join to node 1.

What is the expected result?

The expected result is that the same snapping distance should be in place when the filter is turned off

Please provide any additional information below. Attach a screenshot if possible.
