Scrolling while marking up in Files on iPadOS

Since the arrival of iPadOS (with many amazing features), I have been very frustrated by one change.

When I want to annotate with Apple Pencil a PDF document in files, my finger is also interpreted as drawing. Previously, I could write on documents with the pencil and scroll through it, multi-task etc. with my fingers independently. Surely when using the pencil one would not want to use fingers to draw/sketch.

Furthermore when going through large documents in Files, resting one's hand on the right side of the screen will make you skip to a complete different place.

Although this may seem minor, when this is the main purpose of the iPad (filling in university lecture notes) and is used frequently it is very frustrating.
