Error encountered when creating a New Custom Graph and attempting to set multiple values in one o (4253465)

Problems occur when attempting to create a custom graph with the following settings:

Graph Type: Bar Chart
Datasource: Mailboxes - Mailbox Activity Details
Category Label Fields: Display Name, Date
Data Label Fields: Physical Messages Sent, Physical Messages Received, Total Physical Messages

The issue arises when attempting to enter multiple values in the Mailbox Email filter using the 'Is in' operator. Some users experience the following error message:

Line: 2453
Char: 3

For others the UI seems to hang with an hourglass cursor.
