[BR Template Editor] More than one templated elements without no space in between, are detected as a single element

[senthuran16]

Description:
More than one templated elements that are not having any spaces in between, are captured in a single element.
Eg:
key1=${value1},key2=${value2} should have two elements: value1 and value2.
But it is detected as a single element, that is: value1},key2=${value2.
