meta queries javascript recursion crashes grafana browser tab

[Dutchy-]

When we create a new panel (on a new dashboard), the grafana browser tab completely hangs.
It's hard to debug because of this, but we can see this in the console:

It's output from grafana-meta-queries, and it very much seems like a recursion problem.

Deleting the data source fixed the problem. Re-adding it breaks it again.

This was the data source definition

  - name: MetaQueries
    type: goshposh-metaqueries-datasource
    isDefault: true
    version: 2
    editable: false

Changing it to not be default also fixes the problem! It may have something to do with being first in the data source list.

Grafana version: 7.5.4 (same problem on 7.5.x)
meta queries version:

installing goshposh-metaqueries-datasource @ 0.0.5
from: https://grafana.com/api/plugins/goshposh-metaqueries-datasource/versions/0.0.5/download
into: /var/lib/grafana/plugins
