Incorrect indentation of CSS declaration blocks in HTML files

[lkintact]

Steps to reproduce

1. Run gvim.exe --clean
2. Copy the following text to the buffer:

<style>
body {
font:
Arial,
Helvetica;
}
</style>

3. Execute :set filetype=html
4. Type =G to indent the text. You get the following result:

<style>
	body {
		font:
			Arial,
		Helvetica;
	}
</style>

Expected behaviour

The result should probably be this:

<style>
	body {
		font:
			Arial,
			Helvetica;
	}
</style>

This is perhaps related:
If under the same conditions I try to indent this text:

<style>
body {
font:
Arial,
Helvetica;
border:
solid
1px
red;
}
</style>

I get the following result:

<style>
	body {
		font:
			Arial,
		Helvetica;
	border:
		solid
	1px
	red;
	}
</style>

While the expected result is this:

<style>
	body {
		font:
			Arial,
			Helvetica;
		border:
			solid
			1px
			red;
	}
</style>
