Calligraphy tilt direction reversed

open Inkscape version 1.0.
select Calligraphy tool
with default angle (30°), draw a letter A. Notice how the right leg is thicker.
set angle to be determined by stylus tilt and draw another A. Notice how, if you are right-handed and holding the stylus in a natural writing position, the left leg is thicker.

strokes across (perpendicular to) the tilt of the stylus are thick, but strokes in line with the tilt are thin. This is the appropriate behavior to emulate a sharpened lead pencil used for shading, but wrong for a calligraphy pen.

behavior should model a calligraphy pen tilted on an axis defined by the wide dimension of a calligraphy nib. In other words, strokes perpendicular to the line of til should be narrow, and strokes in line with it should be wide.

Inkscape Version: Behavior is correct for me with distro packag version 0.92, incorrect with version 1 and also AppImage version 1 (and also version 0.92 on Windows, as I recall)
Operating System: opensuse
Operating System version: tumbleweed (rolling release current as of 20200507 including linux kernel 5.6.11)
tablet is XP-Pen Artist 15.6 Pro, used with developmental branch of digimend driver for tilt support. If behavior is correct with all other tablets, please advise and I'll pass along to digimend dev.

with a real calligraphy pen, increasing pressure doesn't make a wider line but does make a darker one
