Can confirm in 21w41a.
Relates to MC-2588 since both have the same causes, but I don't think that resetting the breaking animation while using a tool is an expected behavior.
This doesn't only happen with mending. When any data on your pickaxe (or any other item) changes the game will see it as a new item and reset your mining progress. To fix this Mojang would have to implement a check to check if the item w/ the data modification is actually still the "same" item and if it isn't, only then reset mining progress...
Confirmed for 23w43b. I've used the new tick rate feature to video-record the mining progress resetting multiple times for a single block due to XP orbs being picked up:

Adding this here since I didn't see this when I searched...
Mining with a damaged mending pick can sometimes be interrupted by picking up experience orbs, causing the mining to restart.
The only item with mending is the pick I am using to mine. A video of the issue can be found at https://youtu.be/P3kuJOVuWIk
The issue occurs a couple times, but the most obvious are at 0:23, and the iron block at 0:29.
Let me know if you need to know any other details.
Thanks!
