This is a feature of JavaScript itself, not JMeter.

This is deliberate.

If you include spaces in a variable definition, they will be
preserved, trailing or not, unless they are removed by a function
call.

JMeter takes the contents of the field, and replaces any function
calls with the result of calling the function.

The spaces after the function call are not passed to the function.

One can use multiple functions, nested if necessary, as well as plain
text characters in JMeter variable definitions.
