Is this something that we could add a test for?

[AakashGfude]

@choldgraf we can test this as a part of a latex build in test_transform?

[choldgraf]

sure - I just wanna make sure that the bug we think we are fixing doesn't re-surface :-)

[AakashGfude]

Hey @choldgraf , what do you think about the test added?

[choldgraf]

it looks good to me - is it a test that would have failed w/o the copy method?

[AakashGfude]

@choldgraf , yes it would not have been able to replace <CelloutputBundleNode> with specific mime-type nodes. And would have failed

[choldgraf]

Great - I'll merge tomorrow AM unless somebody else suggests otherwise 👍 nice job @AakashGfude !
