Accessibility Issues: Links must have discernible text

[sigccil]

HI! 

We're currently in the process of updating our applications to meet WCAG accessibility standards and are reviewing all of them as part of this effort. You may have seen my other post. Per our ESRI solution engineer has recommended that we post all issues in the community forum in addition to opening tickets. We're trying to collaborate and raise awareness of the issues we're seeing in our applications. We want to highlight ones that can be easily resolved by users and which ones fall under ESRI's purview.

Issue: 

This one is tricky because in Dashboards we can edit links through the Source button and view the HTML. I tried adding the aria-label attribute to the a tag, but Dashboards won't let me save these changes. Are aria-labels something that Esri handles on their end, or am I missing a step when adding these tags in Dashboards?

As always, any help would be appreciated! 

Steps to reproduce in app:
