Properties Panel captures mouse scrolling inside fields
The Properties Panel inside InDesign 2019 is meant to be the new central location for most of the common settings in InDesign. So it is accessed pretty frequently by most users on a daily basis.
However if you happen to use InDesign on a low-res monitor, or have increased UI text for accessibility purposes, or even just use InDesign in a non-maximised window, it suffers from a big flaw.
These scenarios require the user to scroll the panel up or down to access hidden properties. However, the mouse scroll action is inadvertently captured by the various fields on the panel, and this automatically adjusts whatever is inside them, often without the user realising this has occurred.
The consequence of this is that regularly, the wrong fonts, text sizes, padding measurements etc are randomly dropped into a document, and tend to go unnoticed until it's too late... This probably happens in other panels as well aside from Properties.
Please Adobe, switch off this mouse scroll capture on all panel fields (or make it an option in preferences) so we don't end up sending massive amounts of mistakes to the printer thanks to bad UX design.

Important usability issue indeed. An alternative would be to have to press 'command' with scroll in order to change the panel fields, instead of just mouse scroll.
