Evergreen tries to inexplicitly strip out dollar signs when adding Total Balance to Current Bills Receipt

Evergreen version 2.8.1
Scott Thomas posted a question to the general mailing list regarding the display of total owed on the bills_current receipt.
Here is the link to the conversation:

Assuming the library makes use of print_win.js and doesn’t adjust the Library Setting: Printing: Custom Javascript File, the potential workaround would be:
Lineitem:
<dt><b>Bill #%mbts_id%</b></dt>
<dd> <table>
<tr valign="top"><td>Date:</td><td>%mbts_xact_start%</td></tr>
<tr valign="top"><td>Type:</td><td>%xact_type%</td></tr>
<tr><td>Title:</td><td>%title%</td></tr>
<tr valign="top"><td>Last Billing:</td><td>%last_billing_type%<br/>%last_billing_note%</td></tr>
<tr valign="top"><td>Total Billed:</td><td>$%total_owed%</td></tr>
<tr valign="top"><td>Last Payment:</td><td>%last_payment_type%<br/>%last_payment_note%</td></tr>
<tr valign="top"><td>Total Paid:</td><td>$%total_paid%</td></tr>
<tr valign="top"><td><b>Balance:</b></td><td><b>$<span sum="bal">%balance_owed%</span></b></td></tr>
</table><br/>
Footer:
</ol>
<b>Total Balance: <span sumout="bal" fixed="2"></span></b>
<hr />%SHORTNAME% %TODAY_TRIM%<br/>
<br/>
However, Evergreen is trying to inexplicitly strip out dollar signs. So, it's effectively striping out the first character if that character is not a minus sign or a digit. The end result would be, for a patron who owes you .70 cents; the Total Balance would read $70.00.
The problem exists within this bit of code: newVal = newVal.replace(/^[^-0-9]/,”).

Jason Etheridge has created a fix.
