Short description of error
When you scale around the median point with x axis mirroring enabled, the result is not calculated from the median.
Exact steps for others to reproduce the error
see video.
Add circle mesh
turn on x axis mirroring (or any other axis)
scale around the median
It will give an unexpected result (unless you have topology mirror also enabled)
This does not work the same as 2.79 (excluding the extra axes of course)

I can confirm the issue. Looks like not all selected vertices are used to compute the median point.
Assigning to @mano-wii, because it might be caused by

(haven't tested),Mirror symmetry gives unexpected resultsto Pivot Center doesn't compute mirror elementsHere a less invasive solution to fix this problem.
The idea is to change the
TrasData->center
of objects with mirror elements.This changes the behavior of individual origins when the mirrored elements are also selected, but I don't consider it a regression. (The solution may also ignore this particular case).
