Dashboard Notes Widget blank

Created a Dashboard with one Notes widget with an embedded iframe to the following URL https://threatmap.fortiguard.com/

Updated the Widget title and save. Notes widget still shows “Notes” as the title and the iframe is not rendered. Getting “Uncaught TypeError” in dashboard.js

dashboard=14:1049 Uncaught TypeError: Cannot read property ‘error’ of undefined

at Object.error (dashboard=14:1049)
at c (jquery.min.js:4)
at Object.fireWith [as rejectWith] (jquery.min.js:4)
at k (jquery.min.js:6)
at XMLHttpRequest.r (jquery.min.js:6)

Not sure… but not all web pages support to be in iframe.

I have tested the threatmap in an iframe. Works well. It’s not just the iframe tags. I get the same error when trying other html tags and straight text. Nothing renders.
