Currently, the user is upgrading the script runner plugin from 22.214.171.124-p5 to 6.9.0.
In 126.96.36.199-p5, user can input the LOWER issue key to search issue. Please refer to lower-case-found.png
However, in 6.9.0, the user must input the UPPER issue key to search issue. Please refer to lower-case-not-found.jpg and upper-case-found.jpg
It would be great if the user can search issue key by using lowercase as well in issue picker field.
