Wiki bad link and fix included
Just missing a /
The correct link is:

Where is this bad link located?

Sorry, I was tired.
It is on the page


Why can’t I post a URL that is visible as text?
What is the method to just show the text version?

Better to show the text location on the page that has the error.

/Decor/Vectors – Basic Vector decor showing the Raised/Sunk effects.
Page: Window Decorations

URL generates a preview, but doesn’t show as text.

I fixed the link. In the future try to make better bug reports so it is easy to test and find the bug.
