Comparing your original to my posted copy of your original, it looks like Delphi editor has broken up and re-ordered several [<div class=] tags which seems to be the problem.

FWIW

How do we bypass the div tags?

The Delphi editor modifies them, so you'll have to remove them or replace them with other tags that the editor won't modify.

Edited to add: Or get Delphi to modify their editor and allow those tags "as is"... unmodified!

FWIW

We have to live with the editor we have now.

Then you will have to remove the offending tags.

FWIW

Well that's fine if you have access to source.

However this is a bug for tech to work on, not the user.

Still jumps to the top for me on iOS safari iPhone too.

Try this... tap on the icon and paste in the link, tap OK.

You might see this, just a blue line.
 

Without tapping in the compose area, tap on your embed icon again... it will still show the link, just tap OK again.

It works for me. And does so on any forum (Zeta or Classic) with desktop and other browsers.

When you pass this on to tech can you tell them I've had this problem in only some forums for ages... no one else reported it (I may have via Cstar... so quite a bit ago) and I had a work around so it dlipped my mind.

It's currently and suddenly happening to users at the midnightcastle forum (the article embeds not publishing) and the work around works for me there. 

I get the same thing. The blue line moves the cursor to the top and it embeds there.
