Setting the innerHTML property in an unsafe manner raises issues in
Windows Web Applications. Strings being passed into innerHTML cannot
include the name attribute.

IE11 fixed the checkbox defaultValue issue but not textarea. Rather than
creating a new detect name I'm reusing the old one to protect anyone who
is unwisely using this externally. Re-fixing the defaultValue when it
doesn't need to be done is not a problem, so leave that code for IE11.
Fixes#14716
