Provide detailed reproduction steps (if any)

1. Open editor and switch to source mode
2. Try saving using editor toolbar button

Expected result

Saving with toolbar button should be possible in wysiwyg and source mode.

Actual result

Saving with toolbar button is only possible in wysiwyg mode.

Other details

• Browser: Any
• OS: Any
• CKEditor version: 3.0

Initially this plugin was supposed to work in wysiwyg and source:

but it has most likely been made to work in wysiwyg only by mistake:

Except for this "won't fix" ticket https://dev.ckeditor.com/ticket/10902, I haven't found any problems related to it.

Setting both modes to be dependent on form existence should fix this problem:
command.modes = { wysiwyg: !!( editor.element.$.form ), source: !!( editor.element.$.form ) };
