Unable to "use" shovel when holding a shield

When I hold a shield I cannot “use” a shovel (i.e. right click) to create a dirt path, for example. Worked in Java version 26.2 without problem. Loading the same world in 26.2 without changing anything and creating a dirst path with the shovel does not work.

Removing the shield from the off-hand solved this issue, then I can “use” the shovel again to create a dirt path.
