We are using Sitefinity version 10.1.6500.0 to build a site. And we noticed that the RADEditor in Content modules (like Lists, Content Blocks, Blogs, any dynamic modules,etc) strips a <a href="mailto:firstname.lastname@example.org">Som Text</a> of the href tag. It doesn't occur if there is normal url inside the href.
We also noticed that this issue is present in 10.1.6502.0 (created a new project to test) and that this issue is NOT present in 10.0.6411.0 where it works perfectly fine. Can you guys please clarify if this is intentional? If yes, how do we go around it?
