Browser version fails to load XLSX file if cell contains ">"

[arxcode]

If I try to upload the Excel file Test_with_greater_than.xlsx with the in-browser variant of xlsx-populate (e.g. here but also with the latest version available via bower), I receive an error message:

IQc is not defined

The attached Excel file is a very simple file which just contains a single sheet with a ">" (greater than) sign in the first cell. You get the same result with "<" (less than) and also "&" (ampersand). I have created it with Microsoft Excel for Mac 16.12; however, the same results can also be achieved by using xlsx-populate to write a greater-than sign to a sheet.

I tried in Firefox 59.0.2 and Vivaldi/Chrome, so I think it is not a browser-specific glitch.

Running the debugger, it says the second line of the following the source is to blame:

  function parseEntity (parser) {
    var entity = parser.entity
    var entityLC = entity.toLowerCase()
    var num
    var numStr = ''

I think this is the same issue as #115, as it also gets the "IQc" error. And in turn I think it is this issue from the sax.js repository:

isaacs/sax-js#223

They say it was a bug in UglifyJS (mishoo/UglifyJS#2783) and has been fixed there. So maybe it would be sufficient to re-uglify with a newer uglify?

Please try with v1.17.0. There is also a non-minified version available now.
