Describe the bug

Here's what I run:

$ forge install ProjectOpenSea/seadrop

then I put remappings.txt in my root project as shown on the pic (right side), the other one is from opensea's drop repo (I create another issue see the left side of the pic).

What I notice is this:

1. In the seadrop's remappings.txt, the openzeppelin-contracts remapped to openzeppelin-contracts/contracts
2. but in the forge remappings output, the /contracts was missing.
