after upgrade from 1.642.2 to 1.651.2 (LTS) some variables are not visible in other jobs/templates.

to repeat on 1.651.2:

• create empty job
• add empty string parameter (GIT_REPO in our case)
• in shell step do "echo ${GIT_REPO}"
• test it, should work ok

then

• move code "echo ${GIT_REPO}" to another job
• add that job to "use builders from another project" step in first job
• run it, actual result will be "${GIT_REPO}" instead of value

it works with 1.642.2 but not with 1.651.2. the workaround is to duplicate template logic to every job using it.

is it some expected security fix or bug?
