Describe the bug
When forcing a content ID in the source code view of the WYSIWYG editor, the content ID will be automatically overridden by the pre-generated one.

Steps To Reproduce

Create a new page, and fill it with some content.
Assign an ID, different than the automatically-assigned, to any piece of content, such as a paragraph or a callout.
Save the page.
Open your browser inspect tool or the source code view in the editor and see your custom ID reverted to an automatically-generated one.

Expected behavior
The custom ID should persist after being saved.

My Configuration:

BookStack Version: v0.28.0
PHP Version: 7.3.14
Hosting Method: Docker

Hi @devSparkle,

Thanks for reporting this issue.
I've had a dig into this and it looks like this was more of a fault in our documentation; ID's must be set with a prefix of bkmrk so something like bkmrk-custom-id-value.

I'll update the docs shortly to reflect this.
