Flow 14 and IE 11.0.9600.19356

Due to a restricted environment our customers currently use for testing (Windows Server 2008 R2 via Remote Desktop), we only have access to a very old IE version from 2013 (11.0.9600.19356). I know the release document specifically states that only IE versions on Windows 7 - 10 are supported, I thought I share my experience with Vaadin 14.0.0.rc3 and this IE version.
So using the recommended vaadin-maven-plugin settings (copy-production-files and package-for-production) there is only a blank screen displayed in IE.
Using F12 and reloading the page results in the attached error.
However, adding this configuration to the vaadin-maven-plugin:

	<configuration>
        <minify>false</minify>
        <bundle>false</bundle>
        <hash>false</hash>
    </configuration>

solves the problem and the application GUI is displayed by IE.
So it seems to me that Vaadin is working OK, but minify does something that breaks IE.
