I was experimenting in D8 with filters on text-formats to understand why i was not seeing CSS i had placed in a block.
Turning on and off Limit allowed HTML tags and correct faulty HTML and Correct faulty and chopped off HTML i saw that the limit filter was not only applied to the output, but the results were also saved to the block. That's in contrast to the description on the text-format config page:
A text format contains filters that change the display of user input
Then when i saw that without any filters on, a
<:style> tag was turned into
<:style type="text/css"> it became clear that CKEditor was doing his thing too...
Sure enough, after disabling the editor, the limit filter only altered the output.
Now, my questions:
Is this described behaviour all as intended? If so, what's the logic? And, shouldn't the fact be described in the UI that enabling an Editor changes the filter's behaviour?
Or is this a bug?
