Add HTML Support for "title" tag in AGOL Pop-Ups

[NedCake1]

The title tag allows you to create hover text for an image in a pop-up. Hover text is very useful for graphics like park icons. The sample below works great until you save and refresh the feature layer. ArcGIS Online automatically strips out all references to unsupported tags. Why isn't this tag supported?

<img alt="" src="{expression/expr10}" title="Playground" />

Yep very familiar with this page.  Want support for "title" added to this set unless there is a really good reason why they can't support it.

Thanks

I wish there were quite a few more options supported as well!

ability to support full html css in popups and allow for arcade to inject it would really open up possibilities, especially for attribute data to drive the appearance and behavior of popups.  A great first step in that direction would be adding some basic elements like Title though that are absent to that short list of supported html.

I add title tags a lot of places for tooltips. They are very helpful.  Generally it would be good to support this tag through the popup and html rendering from AGOL.  The main thing though I want is for a title tag, is a tooltip on-hover over my popup's titlebar, saying 'Drag the titlebar to move this info box' or similar.  Since I always make my popups movable.  Anyone have good advice how to achieve this, to create a title tag tooltip on a WebApp Builder Dev Edition popup's titlebar?

 Would really like to see this supported, as hover text is important for symbols in the popup (as shown in the original post).

This one gets my vote too.  Anything to improve accessibility is a no-brainer IMHO.
