Horses don't move when being tamed

OK...

So I just tried with the newest snapshot... 16w07a

Horses still just stand there when you mount them during taming. you get bucked off and then they rear

in riding, the horses jump forward OK

But after you ride around for a while, and you dismount, they take damage

also, if you have ridden for a while and then remove the saddle, they also take damage

Most of these issues have been reported already. I removed those from your report. In the future please only report one issue per ticket.

I tried again in the pre release and it's a tiny bit better but not really

Confirmed for 16w14a

This issue also affects pigs.
And confirmed for 1.9.3-pre1.

In 21w17a

Can confirm for 21w18a

In 1.18 Pre-1

Still a thing in 22w05a

I'm not sure when, how, or why, but it seems this bug was fixed at one point. I just tested it on 1.19 Pre-2 and it matches that of the old horse taming behavior!
