Root cause for failing test for `testMangledIntsBytes()` in `ParserErrorHandlingTest`

[harsha-99]

I was looking at the failing tests directory and was trying to debug the failing tests in ParseErrorHandling105Test.java file, I realised there was a similar test commented out in ParserErrorHandlingTest.java under package com.fasterxml.jackson.core.read in line 29 i.e. _testMangledNumbersInt(MODE_DATA_INPUT);
I saw a comment wondering how _testMangledNumbersFloat(MODE_DATA_INPUT); was working.

With my investigation I found out that during _testMangledNumbersIn() execution, _verifyRootSpace() in line 1088 of UTF8DataInputJsonParser.java gets called with _nextByte = -1 and hence satisfies the condition in line 1278 i.e. if (ch <= INT_SPACE) hence doesn't throw a missing WS error. Where as for _testMangledNumbersFloat we set the value as _nextByte = c; in line 1257 and hence it would throw the exception.

I hope this explains the root cause of the issue, happy to receive any feedback or suggestions. Apologies for my verbose explanation.
