P: if the brush is resized in between changing a slider and making the first brush stroke, the slider resets to zero

I can confirm that I am experiencing the exact same issue since version 18.3.1. I have the "Automatically reset sliders" option enabled, but in older versions, they would only reset when creating a new mask after pressing the "K" key. Now, it doesn't just affect the Highlights slider—all adjustment sliders reset to zero if I right-click to resize the brush before making the first stroke on a new mask. Please escalate this to the development team, as it severely disrupts the retouching workflow.
