The callback function OnRemoveWithReason suddenly stops being called, even though there is new data being written

[fang2329]

bigCf := bigcache.DefaultConfig(5 * time.Second)
bigCf.OnRemoveWithReason = hdl
bigCf.HardMaxCacheSize = size

"I'm certain I configured OnRemoveWithReason and it had been triggering callbacks continuously, but for some reason it suddenly stopped. Monitoring confirms data is still being written and the process hasn't panicked."

Environment:

• Version (git sha or release): v3
• OS (e.g. from /etc/os-release or winver.exe): ubuntu 16.04
• go version: 1.20

During testing, we found that reinserting the currently removed key within the OnRemoveWithReason callback causes permanent cessation of all subsequent OnRemoveWithReason callbacks.
