Allow permissions within iframe element.

[cpreston321]

The example I can think of is Icones. I open it within nuxt devtools then I click 'copy to clipboard' then does nothing.

Example to make this work would be to add

<iframe src="index.html" allow="clipboard-write"></iframe>

Reference here: Permissions Policy

Could leave it up to the developer within addCustomTab within the iframe settings for more flexibility or just make it static for a quick fix.

Thank your for looking at it @cpreston321

Since it's for development, I guess it's good to add it for each iframe, happy to open a PR?

Same, I think we could have most of the reasonable permissions on by default

[cpreston321]

@atinux will do. I can add PR now. For permissions what are we thinking enabling by default?
