I was playing with the URL as explained in https://observablehq.com/@jashkenas/url-querystrings-and-hash-parameters
and I wonder if there is bug somewhere in how Observable manages the clicks on local links, or if I missed something, but I crashed the notebook by clicking successively on the links created with:
html`<a href="${document.baseURI}#a">👉 clic here</a>`
and
html`<a href="${document.baseURI}">👉 then here 💥</a>`
