Line break with Multi-Select Fields [solutions]

Hello,
Just a little note concerning multi-select fields displayed as comma separated lists.
In narrow columns the display of multi-select field values may distort the layout, because the version 1.5.3c inserts 'comma + non-breaking space' as the value separator for comma separated lists. That may result in multiple values to become one long unwrappable string.

How to resolve it:
Solution A)
Select custom separator and enter '& # 3 2 ;' (without the spaces)
Disadvantage: the first time you save or apply field parameters this decimal entity is converted to a space character. If you change something again, the space is trimmed/removed. So you have to remember to enter the HTML entity for a space each time you configure this field type.

Solution
Edit /plugins/flexicontent_fields/selectmultiple.php
and replace in line 193
$separatorf = ',& nb sp;';
with
$separatorf = ', ';

If have not done any extensive testing. There might be a reason to use a non-breaking space here, but changing this line, resolved my formatting issue with comma separated lists.
I'd suggest to consider changing this in the core code.

Have a good day
