This Pull Request addresses a race condition in the updateIframeHeight
function where it is sometimes called when the iframe is not fully
loaded or accessible resulting in an alarming error message for the
user.
To address this we:
1. Add defensive programming within the updateIframeHeight function
2. Delay instantiating the intersection observer until the iframe has
loaded

Update mermaid to
[v11](https://github.com/mermaid-js/mermaid/releases/tag/v11.0.0) and
enable the new [`suppressErrorRendering`
option](https://github.com/mermaid-js/mermaid/pull/4359) to ensure
mermaid never renders error elements into the DOM (we have per-chart
error rendering, so don't need it). Tested various chart types.
BTW, I was unable to reproduce that error rendering from mermaid with
`suppressErrorRendering: false` and I thought we had some CSS to hide
the error element, but I could not find it, not even in git history.
None of the frontend js/ts files was touched besides these two commands
(edit: no longer true, I touched one file in
61105d0618
because of a deprecation that was not showing before the rename).
`tsc` currently reports 778 errors, so I have disabled it in CI as
planned.
Everything appears to work fine.
