Inconsistent behavior for inline html tags

[meteorlxy]

We have some examples for raw html:

commonmark-spec/spec.txt

Lines 9006 to 9030 in ab56f2e

	```````````````````````````````` example
	<a><bab><c2c>
	.
	<p><a><bab><c2c></p>
	````````````````````````````````
	Empty elements:
	```````````````````````````````` example
	<a/><b2/>
	.
	<p><a/><b2/></p>
	````````````````````````````````
	Whitespace is allowed:
	```````````````````````````````` example
	<a /><b2
	data="foo" >
	.
	<p><a /><b2
	data="foo" ></p>
	````````````````````````````````

Which shows that it is supported to split a html tag into multiple lines. However, there is an inconsitent behavior when spliting a <img> tag:

Reproduce link

• When writing in a single line, it's recognized as a html block.
• When writing in multiple lines, it's recogized as inlined html.

This isn't inconsistent; it is just following the spec.
Have a look at the spec for raw HTML blocks.

Your first example is a type 7 HTML block.

Your second example is not an HTML block. (Note that img isn't in the list for type 6.)
