Comment:
Why not using src attribute with dataURI ? It's supported by all browsers  :
<iframe
src="data:text/html;charset=utf-8,%3C%21DOCTYPE%20html%3E%3Chtml%20lang%3D%22e
n%22%3E%3Chead%3E%3Cmeta%20charset%3D%22utf-8%22%2F%3E%3Ctitle%3E%3C%2Ftitle%3
E%3C%2Fhead%3E%3Cbody%3E%3Cp%3Edid%20you%20get%20a%20cover%20picture%20yet%3F%
3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E"></iframe>

We can replace this:

<iframe seamless sandbox srcdoc="<p>did you get a cover picture yet?"></iframe>

By:


<iframe seamless sandbox src="data:text/html;charset=utf-8,%3C%21DOCTYPE%20html%3E%3Chtml%20lang%3D%22en%22%3E%3Chead%3E%3Cmeta%20charset%3D%22utf-8%22%2F%3E%3Ctitle%3E%3C%2Ftitle%3E%3C%2Fhead%3E%3Cbody%3E%3Cp%3Edid%20you%20get%20a%20cover%20picture%20yet%3F%3C%2Fp%3E%3C%2Fbody%3E%3C%2Fhtml%3E"></iframe>

And it's supported by all browsers :)

Does the second of those snippets in comment 1 really seem better to you than the first?

Yes, for now data: URLs are better because they work more. But in 20 years, I think life would be better if we're using the cleaner and easier-to-escape version rather than data: URLs.
