Disconnect not removing all references?

[schorlton-bugseq]

Thanks for the great library! Running gfapy 1.2.3 on the following file:
test.gfa.gz

g = gfapy.Gfa.from_file("test.gfa", vlevel=3)
gfa_line = g.line("k141_11431")
gfa_line.disconnect()

Based on the docs, I expected all lines referencing k141_11431 to be removed. Indeed most lines are. However, there is still one line below...am I understanding the library correctly? Thanks!

for line in g.lines: print(line)
