Locking multiple hitpoints locks filtered hitpoints

Cubase Pro 15.0.30 on Windows 11.

In the sample editor, raising the hitpoint threshold makes hitpoints below the threshold disappear, but with their triangle still at the top under the ruler - the manual refers to these as “filtered”. If I now select multiple hitpoints via the tool modifier I will lock hitpoints that are filtered. My expectation is that it would only lock visible hitpoints.

Can anyone confirm this behavior? Or disagree with my expectation?

Thanks.
