poetry lock --no-updates still updates a single dependency #5314

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Fedora 35

Issue

One of my dependencies is sentry-sdk which is at the moment locked to version 1.5.4 (the latest version of that package is 1.5.7). Whenever I run poetry lock --no-updates the locked version in poetry.lock changes to 1.5.7 even though I would expect it to stay at 1.5.4. What's more interesting is the fact that the issue goes away if I change the definition of the dependency to:

sentry-sdk = "^1.4.1"

Is there something I don't understand about poetry lock --no-updates that makes it behave this way?
