@e111077 something is wrong with the indentation of the code sample on the home page, even thought I don't think that's using the playground.

[e111077]

oh did i not push that change up?

[e111077]

oh no it's minifying!

The editing experience is sooo much better! Confirmed it works well in Safari too. Haven't checked Firefox yet.

I did notice one new issue with the playground: if you edit a playground, then switch to another sample, you'll get an alert about unsaved changes. Click OK to continue and then switch samples again and you'll get the alert again even though you didn't edit the new sample. Once in you're in this state the alert shows every time you switch a sample. This does not happen on the deployed version.

@justinfagnani This seems to be an upstream issue. It's firing a change event when the document changes. Working on a PR right now

google/playground-elements#433

can't 100% confirm this is the fix because npm ln fails at runtime due to global mwc custom element define calls

[e111077]

Bumped playground elements and I cannot repro. Can you please double check, @justinfagnani? I’m deving on an iPad and safari is a bit odd.

works good from my testing on Safari 26.0.1

[justinfagnani]

Same, look good here
