Steps to reproduce
const doc = new jsPDF({ unit: 'mm', format: [200, 200], orientation: 'p' }) // with unit: 'pt' it works as expected
doc.advancedAPI()
doc.beginFormObject(-50, -50, 100, 100, doc.unitMatrix)
doc.rect(-50, -50, 100, 100).fill()
doc.endFormObject('0')
doc.doFormObject('0', new doc.Matrix(1, 0, 0, 1, 100, 100))
doc.setDrawColor(255, 0, 0)
doc.rect(50, 50, 100, 100).stroke()

Issue
The width and height of the bbox are scaled with the inverse scaling factor:

var getPageWidth = (API.getPageWidth = function(pageNumber) { |
|
pageNumber = pageNumber || currentPage; |
|
return ( |
|
(pagesContext[pageNumber].mediaBox.topRightX - |
|
pagesContext[pageNumber].mediaBox.bottomLeftX) / |
|
scaleFactor |
|
); |
|
}); |

x and y are not scaled.
The expected behavior is that x, y, with, height are all scaled by the normal (not inverse) scaling factor. This way the values passed to beginFormObject are actually interpreted with the correct unit.
This issue came up in yWorks/svg2pdf.js#244.
