Standard meta tags wrongly escaped inside "simple2.html" file

Hi All!
I think there is an error in file "simple2.html" (test/templates/simple2.html) that invalidates the result of some tests like "Engine Test".

I notice that for test case "Engine Test" you compare the compilation of "simple2.htl" with the "simple2.html".
But if I do a manual comparison of the two files I can see a very interesting difference in some meta tags of the page.

```diff
>> FILE simple2.html
-
-
-

>> FILE simple2.htl
+
+
+
```

Maybe I missing something, but why standard meta are escaped? They are not inside an HTL context.
shouldn't they be kept as they are in "simple2.htl" file?

Thanks
M
