Subject: [PATCH 1/2] fix bug where part of template annotation line was not
 stripped

In https://github.com/ViewComponent/view_component/pull/2541, logic
was added to strip out the first template annotation line. Unfortunately,
the template annotations in Rails span multiple lines, causing
invalid Ruby to be eval'd.

This fix splits the compiled source on ";", which properly isolates
the template annotation for easy removal.
