I tried to add some HTML text content (see the following html) in the pop-up of ArcGIS Online Webmap. All the tags and attributes used are listed in the Supported HTML webpage and should be respected and supported in ArcGIS Online in general. However, I found that some content in the style attribute were silently removed when I inspect the pop-up using DevTools in Chrome (see attached figure).
How can I fix this bug?
