[JENKINS-66345] Global variable in shared-library is missing after jenkins restart

I have defined global variable as doc: https://www.jenkins.io/doc/book/pipeline/shared-libraries/#defining-global-variables

@​groovy.transform.Field

def yourField = [:]

This is the problem:  Jenkins is restarted when one pipeline build is running, after jenkins is back, the global variable defined in vars/test.groovy because empty.

The following is the logs of pipeline build:

16:12:28 {~~~~~~ globalReference defined in pipeline:={PRD_MODE=, job_start_time=1628583133894}}

[Pipeline] echo*16:12:28* ~~~~~~~~~[test] defined in vars: foo

[Pipeline] echo*16:12:28* ~~~!!!!! lib object:org.jenkinsci.plugins.workflow.libs.LibraryStep$LoadedClasses@​116dced

[Pipeline] sleep*16:12:28* Sleeping for 1 min 40 sec

Resuming build at Tue Aug 10 08:14:27 UTC 2021 after Jenkins restart

 Ready to run at Tue Aug 10 08:15:14 UTC 2021*16:15:14* No need to sleep any longer

[Pipeline] echo*16:15:14* ~~!!!!! after sleep lib object :org.jenkinsci.plugins.workflow.libs.LibraryStep$LoadedClasses@​232cdd2e

[Pipeline] echo*16:15:15* sleep back [test]defined in vars : null

[Pipeline] echo*16:15:15* {~~~~~ globalReference defined in pipeline:={PRD_MODE=, job_start_time=1628583133894}}

The value in vars is missing, but the globalReference defined in pipeline is ok.

environment

```
jenkins 2.263.4

Pipeline: Groovy 2.91
```

Start with the shared-library example in vars/test.groovy and reproduce the pipeline using the reported Jenkins 2.263.4 and Pipeline: Groovy 2.91 environment. Compare the global variable before and after a Jenkins restart, using the log sequence as the expected failure case. Done means the variable retains its value after resumption, with a regression test covering the restart scenario.
