[JENKINS-52347] multi-line bat step isn't executed within a single console session

Executing a step similar to the following fails:

---

steps

{

  bat returnStatus: true, script: '''

  SET PATH = %PATH%;"C:ʅʅsomeʅʅpath"

  PATH'''

}

---

 

(I had to use special characters above because double back-slashes aren't displayed correctly by Jira.)

 

 The path is not being set:

---
