It isn't really a fix for the mentioned bug but it slightly improve things. In reducing the memory use, the time spent in the GC is reduced either.
The algorithm to compute the bounding box is the same as before but it has just been rewritten to be more efficient.

@Snuffleupagus, in the failing tests (I'm fixing) the line number where it occured is very wrong:

2) annotation InkAnnotation should render an added Ink annotation for printing
  Message:
    Expected $[1] = 2 to equal 1.
    Expected $[2] = 1 to equal 2.
  Stack:
        at <Jasmine>
        at UserContext.<anonymous> (file:///home/runner/work/pdf.js/pdf.js/build/lib-legacy/test/unit/annotation_spec.js:3052:38)

I don't remember having such issues in the past, could it be related to #17563 ?

Lots of ref-test failures.

Wasn't that bug eventually filed in #17589 and fixed shortly after in #17596?
