Line length shrinks if Matrix element is used when TWISS is called

[eccortes95]

A line with a MATRIX element, eg:
wiggler: matrix,l:= 4,rm11:= 1.000449786249,rm12:= 4.000639844715,rm21:= 0.00022577719708,rm22:= 1.00045326313,rm33:= 0.9786569514876,rm34:= 3.970145599493,rm43:=-0.01063922161568,rm44:= 0.97864807445;
from MADX can be exported to Xsuite.
However when I load the line and then do TWISS the line appears to shrink:
line = xt.Line.from_dict(loaded_dct)
tab = line.get_table()
print(tab['s'][-1])
OUTPUT: 2303.952493011991
line.build_tracker()
tw = line.twiss(method='4d')
print(tw0.s[-1])
OUTPUT: 2223.9524930120483

I can provide the lattice, if needed.

Hello. Yes it would be good to have the full lattice

I've sent it.
