It may well be a limit with 2270L DTs, but not clean. I can only imagine they added ramped intakes due to the fact there’s an ADV but that said, barely any fighter currently with variable ramp intakes actually needs them.

The Tornados are limited to ~ M1.3 not because of Hindenburger tanks but because the intakes are fixed. Get over it. The Hindenburgers are subsonic iirc but I can’t be bothered to check.
The Tornado had variable ramp intakes because there was a requirement for M 2+ capability. But that was always on paper. As far as I know, even on check flights i.e. with a completely clean aircraft (no pylons), pilots reached M 1.6, 1.7 tops. Like the data from the manual suggests, surprise surprise.

The B-1B was limited by structure relative toe B1A. B1B was designed to have 1/10th the RCS of the B1A though.

The difference is air intakes. The Su-24 similar to the Tornado and B-1 was a (in theory) M 2+ aircraft, M 1.35 after they changed the intakes to fixed ones.

I also question what that fight envelope you’ve shown is for but it doesn’t say Tornado or GR4 anywhere and the speeds and ceiling is all wrong. Data Basis – Estimated.

It is for an Italian PA 200. I’ll let you figure out what that is. I know it says estimated but that is a hell of a lot better than useless glossy brochure “data”.
Drag index 20 is with 7 pylons only – with Sidewinders and ECM/dispenser pods, drag index is 40, top speed less than M 1.3

Since bot the German and Italian AF statements were not enough for you, here is the manufacturer.http://www.panavia.de/aircraft/overview/

So? Speed limit is M 2.2 just like the manual says.
