Render HTML dependency <meta> tag contents correctly

[jmcphers]

Prior to this change, HTML dependencies that included meta tags were rendered like this:

<meta name="0" content="[object Object]" />

This appears to be because the function invoked in the $.map is being called not with the name and value of the <meta> tag but rather with an object having that name and value, plus an index.

It feels like there should be a more idiomatic way to do this (feedback welcome!).

You could do this - it's not really prettier, but the intent is slightly clearer IMO.

var name = Object.keys(obj)[0];
return $("<meta>").attr("name", name).attr("content", obj[name]);

Could you also add an entry in the NEWS.md?

If you feel confident that this change is safe, I'm happy to merge.

[jmcphers]

Okay, I'll change that, and add the NEWS entry.

My only concern is that this code has existed for about a year and a half in its present form, so either (a) it has never worked, or (b) there's an upstream change or a difference in usage at play.

Okay, should be ready for merge now.
