16907	Iframe plugin uses deprecated attributes and allows invalid values in HTML5	Tomasz Jakut		"== Steps to reproduce ==

1. Open editor with iframe plugin (e.g. http://sdk.ckeditor.com/samples/fullpreset.html ) and clear its content.
2. Click ""Iframe"" button.
3. Set URL to `http://wikipedia.org`, ""Width"" to `100%`, ""Height"" to `800px`, ""Align"" to ""Middle"".
4. Check ""Enable scrollbars"" and ""Show frame border"".
5. Click OK.
6. Go into source mode and copy generated code into https://validator.w3.org/nu/#textarea
7. Validate HTML

== Expected result ==

* Editor should not allow to set ""Width"" to ""100%"" (only digits should be allowed).
* Editor should not allow to set ""Height"" to ""800px"" (only digits should be allowed).
* No validation errors found.

== Actual result ==

5 validation errors are found:
* {{{Bad value 800px for attribute height on element iframe: Expected a digit but saw p instead.}}}
* {{{Bad value 100% for attribute width on element iframe: Expected a digit but saw % instead.}}}
* {{{The align attribute on the iframe element is obsolete.}}}
* {{{The frameborder attribute on the iframe element is obsolete.}}}
