| In response to LinkedIn question from Ben Nadel: | |
| https://www.linkedin.com/feed/update/urn:li:activity:7381052444270567425/ | |
| NOTE: All executions using "cftag (cfscript)" result in both start/end executions being triggered. | |
| FIX: To avoid being double executed in cfscript, we modify the cftag/cfmodule to exit early if `thisTag.executionMode=end` | |
| on implmentations that don't make use of `thisTag.GeneratedContent`. | |
