I saw the most recent update to the new Map Viewer in AGO supports custom HTML, however I've noticed that in-line styling doesn't seem to work as expected if I'm using a table element.
Below is an example. If I try to add a second style to the in-line style, setting the font color to red, this style does not hold and disappears when I go back to look at the HTML view.
1 - Add the style
2 - View the custom pop-up --- font color is not red.
3 - Look at the custom HTML again --- the color tag is no longer there.
It does seem to work as expected for other elements though, for example, divs, as shown below. Is there any reason that table are treated differently? Is it because they are automatically placed within a <figure> element?
