When using HighlightingCompositeConverter or custom one we get LOGBACK: No context given for ch.qos.logback.core.spi.ContextAwareBase

Please use attached
logback-spring.xml.txt
sample logback-spring.xml to reproduce the issue.
This issue is when we use 'highlight' conversion rule, same is the case with the custom conversion rule as well.

[spring-boot version 2.5.2]

Thanks for the report, but this does not have anything to do with Spring Boot.

The same output is produced with the following:
