Most histories of the Bill of Rights gloss over ratification in a sentence or two. Here is an article from the Santa Clara Law Review which discusses the matter at some length, beginning on Page 920. It doesn’t address the OP’s question directly, but provides some tantalizing hints of an answer.
As the article notes,
This is one reason for the paucity of historical attention. However, the author then goes on to discuss the debates in Massachusetts and Virginia in some detail. In Massachusetts, the Senate approved amendments 3 through 12 and the House approved 3 through 11.
But, antifederalists in both houses were dissatisfied because the Bill of Rights didn’t go far enough. They appointed a Joint Committee to recommend additional amendments. The Committee recommended twelve, one of which provided that “the states should pay the salaries of federal senators and representatives”.
Context: The notion that the federal government should pay members of Congress was novel in 1789, and not universally accepted, especially by Antifederalists and lukewarm federalists. Under the Articles of Confederation, states had paid members of Congress. This hadn’t worked well; states were broke during the 1780’s and salaries and expense allowances arrived late or not at all. As this site discusses, this is one of the reasons the Confederation Congress (1781-89) had chronic attendance problems. However from an Antifederalist viewpoint, this was a feature and not a bug. If Congress couldn’t muster a quorum, it couldn’t pass obnoxious laws to increase its own power.
So Antifederalists appear to have disliked the Salary Amendment because it “improved” a concept that they wanted to eliminate, namely federal salaries for Congress.
By now you may be wondering, how is it possible that both houses in Massachusetts approved amendments 3 through 11, when every history book says that Massachusetts didn’t ratify the Bill of Rights until 1939? Ah but remember, the Bill of Rights was the first, last, and only time in American history that Congress proposed Constitutional amendments en bloc. The states considered them en bloc. The MA Senate passed a resolution approving ten amendments, and the House nine, and the two houses never reconciled the difference, so as far as Massachusetts was concerned they never properly ratified anything. So they reported to the federal government, and so matters stood.
A similar process took place in Connecticut. So dislike of the Salary Amendment and the Reapportionment Amendment not only sank those two amendments, it delayed (and could have prevented) ratification of the other ten as well.
The Santa Clara article cites a five-volume opus called Roots of the Bill of Rights, published in 1971, which I will try to track down and see if it sheds any additional light.
