Using the "matches" condition for a scoreboard objective value will give an error

How to repeat:
> /scoreboard objectives add test dummy
> /scoreboard objectives setdisplay sidebar test
> /scoreboard players set @s test 1
> /execute if score @s test matches 1 run say hi
This would work in previous snapshots, but not in this one.
After the matches value, "1", the command won't accept the rest of the execute command.
