Details

Currently, we use the nsITransferable passed for clipboard write as the clipboard cache directly, https://searchfox.org/mozilla-central/rev/338a8ecb357df66ee19e875227d706fb0dde5f30/widget/nsBaseClipboard.cpp#408. This means that if the nsITransferable is modified later, the clipboard cache is also affected. This is error-prone, using a cloned one looks more reasonable to me.

Oh, the DataStruct is not copy-able due to bug 335545.
