P: Zoom with Option + Scroll Wheel with Adjustment Brush (k) broken

The most recent version of ACR broke this function again. Zooming while using Option + Scroll Wheel doesn't work when using the Adjustment Brush (k). It works okay with other tools (Spot Removal (b)  gradient (g) and (j) tools). But when the adjustment brush (k) is active, the scroll wheel adjusts the brush size *regardless* of whether the Option key is pressed or not.

This issue was addressed about a year ago, but one of the recent updates broke it again. Please let me know what else you need to know to get this bug fixed again. Thanks in advance!
