Yes ?

Last I looked DTLS didnt use TCP but UDP ?

Disregarding that:  How does the HTTP/2 layer know that the TLS
layer will in fact put everything in the frame into a single packet ?

The only way you can pad in HTTP/2 in that situation is so that all
frames have the exact same size.

The TLS layer should do that, if that is desired.

Never attribute to malice what can adequately be explained by incompetence.
