The bug
MC-70127 was marked as fixed for 1.20.2 pre-release 1. However, cacti and sugar cane, despite being covered under that ticket, are still affected by the issue.
How to reproduce
Open your F3 screen
Run the command
/gamerule randomTickSpeed 100Place a cactus, paying attention to the right hand side of the screen where it lists block states
Wait five seconds
Right click the cactus
Expected results
The age state of the cactus would increase, which would be reported by the debug screen since you're looking at it and right clicking on the cactus wouldn't do anything.
Actual results
Right clicking the cactus causes the displayed "age" value to instantly increase from 0 to a higher value such as 5, implying that the block's state change on the server was not communicated to the client until a player interaction with this block forced it to update client-side.

Still happening in 26.2 and in 26.3 Snapshot 3
Only tested sugar cane in 26.3 Snapshot 3. Tested in more detail in 26.2, can confirm it affects fire, cactus and sugar cane blocks (which all use age values 0 through 15). Commands and datapack functions show the age value updating as expected, even while the debug screen info remains the same.
Can confirm in 1.20.3 Release Candidate 1
