Run configuration name truncated

Hi, 

Sometimes when the run configuration names are not as short, the pop up truncated them with `...` as shown below, but we still like to know the exact full configuration names. Is there a way to disable the truncation and increase the width of that sub-popup?

Code to generate the run config is at https://github.com/pantsbuild/intellij-pants-plugin/blob/ec84545278463160c71977f789b29a3b3740f723/src/com/twitter/intellij/pants/execution/PantsTestRunConfigurationProducer.java
