Confirmed for 21w06a. At least in 21w06a there is no desync unlike @unknown said. This must have been changed at some point. The flint and steal also uses duribiliy on server side as well as fire charge being consumed. Also note that the build hight limit was changed, meaning you now need to use Y level 319 instead of 255.
Yes, fire charges are consumed above the build limit, there is no desync in that situation. (MC-226055)
Also the item is "used up" when in Survival mode, indicating a client-server desync.
