[Star Trek] During the Dominion War the federation mines the Bajoran Wormhole with cloaked, self-replicating mines. Wasn't the use of cloaking devices i these mines a violation of the Treaty of Algeron?

The Federation is not allowed to develop cloaking technology, let alone incorporate it into mines. Shouldn't the Romulans have been upset that Starfleet personnel built and deployed a cloaked minefield?

Technically, the mines were not created or deployed by the Federation. They were created by Rom, an engineering employee working for the Bajoran provisional government - his direct supervisor was Chief O'Brien, but he was actually employed by the Bajorans, not the Federation. It was similar to the way Odo and Kira both reported to Sisko, but worked for the Bajoran government. 

Bajor was not part of the Federation, and hadn't signed any cloaking-technology treaties with the Romulans.
