Thank you for reporting.

This is actually somewhat intentional.
If you hold the umbrella in your off-hand, it does not protect you from the sun, so it also does not slow you down.
This decision was made to nerf the umbrella. You should not be able to do anything else while holding the umbrella. It is just meant as a last reserve if you really must go through the sun.

However, it is also disabled by default, so maybe we can rethink this decision, or alternatively add a model of a closed umbrella that is used in the off-hand.
