Fix issue with only "-" and whitespace in element

Browse Source 
Fixes: #2198

If there is a single "-" or it is only accompanied by whitespace, then
it wouldn't get escaped as it was detected as as a number. This would
produce invalid JSON.
This makes the numbers part ignore such and thus ensures it gets escaped
as text.

There might be other corner cases related to number parsing, this should be investigated.
