- `KtReadActionConfinementLifetimeToken` tracks its validity via the
project-wide out-of-block modification tracker. Out-of-block
invalidation of some LL FIR session will cause the lifetime tokens of
all analysis sessions to become invalid, including unrelated sessions,
because of this project-wide tracking.
- If `KtFirAnalysisSession`s are only invalidated when their underlying
LL FIR session is invalidated, the cache may expose analysis sessions
which contain invalid lifetime tokens after out-of-block modification.
Even though an analysis session will still be practically valid if its
underlying LL FIR session is valid, the lifetime token will *think*
that the PSI has changed and throw an "access to invalid token"
exception.
- Hence, we cannot currently invalidate `KtFirAnalysisSession`
granularly and project-wide OOBM tracking needs to be restored.
