On various pages at observablehq.com, opening the Web Inspector causes the browser tab to immediately crash and reload the page. I've reproduced this in both Safari 11.0.3 (13604.5.6) and Safari TP 55 (13606.1.15).
Pages that exhibit this issue:
https://beta.observablehq.com/@mbostock/introduction-to-generators
https://beta.observablehq.com/@mbostock/five-minute-introduction
https://beta.observablehq.com/@mbostock/introduction-to-notebooks
https://beta.observablehq.com/@jashkenas/night-skies-lights-and-light-pollution-globe
(Those are the first 4 I tried.)
If the page is loaded with the inspector already open, it does not crash the browser tab. However, if the inspector is then closed, the browser tab does crash.
