[BUG] Comma Seperated Filter Values

[landon-lengyel]

Describe the bug
When using the multi-value filters ("is one of", "is not one of") I found that pasting multiple comma separated values resulted in some strange behavior. Hitting enter only inputs the last value (and results in issues searching). Clicking on the dropdown which says "Add each item separated by ," does nothing.

To Reproduce
Steps to reproduce the behavior:

1. Go to Dashboards, Discover
2. Have a few comma separated values in your clipboard. Such as: 1234,123,12
3. Add a filter, choose a field, and an multi-value operator ("is one of", "is not one of")
4. Paste your values and hit enter, or click on the dropdown.

Expected behavior
The UI would seem to imply based on the text and newline symbol that simply hitting the 'enter' key, or clicking on the dropdown which says "Add each item separated by ," will result in those values being added as separate values. In reality, only clicking away from the operator selection box does that.

This does not happen in OUI and is an OSD specific bug. https://oui.opensearch.org/1.6/#/forms/combo-box

There is a different kind of issue with OUI: Adding 1, 2, 3 to OUIComboBox with delimiter, none of them are added to the options list (in the drop down) but if we delete the pill for the last one, 3, it is added to the options list. However, deleting the other ones, 1 and 2, does not add them to the options list.
