Glitch on initial load of HTML cells

[tennox]

After discovering the amazing starboard-wrap functionality, I did what any insane person would do, and crafted a starboard notebook demonstrating it 😁

But I discovered a glitch when I set the cells to "Run on load", where there is actually a different element returned by document.getElementById, which (I found out via throttling network in devtools) is because the cell editor renders the actual html for a brief moment:

I guess it should render a <pre> with the content instead or something like that 🤔

Workaround (using the last matching element) is shown here:
