Does not work on Quick Edit screen

[tonykim5]

Terms are displayed as checkboxes instead of radios when using Quick Edit.

However, radios are correctly displayed when using Bulk Edit.

Fix: #17

Change line: 438 in class.taxonomy.single-term.php to:

var $editRow = $this.parents( 'tr' ).next().next();

Works for me in WordPress 4.61

I have 2 issues with this code
No.1
The fix doesn't work in WordPress 5.5.1 as it throws an error
Parse error: syntax error, unexpected 'var' (T_VAR) in S:\xampp\htdocs\wp-content\plugins\webt\lib\classes\class-taxonomy-single-term.php on line 438
How do I fix this?

No.2
Without the fix it works fine when I use the quick edit but when I use the Bulk actions -> Edit it removes the taxonomy from all the post selected leaving them without any term (empty)
