I tried the following patch locally which seems to fix it; see screenshot:

The first line, using XmlStringUtil.escapeString, is unrelated but I spotted it when looking at the other code, and it's a useful change to make because the replacement strings in the custom code is wrong (it's missing a trailing ; in each one of those entity strings which is required (and > isn't required to be escaped from text content.)

Thanks for digging through the code! I've sent out a CL to fix it.
