Input box disappears on Calendar dynamic date range n-months

When entering (changing) properties for the Calendar component, one of the input boxes vanishes with backspace over prefilled value.

Environment:

• API Version: V2
  


• Release: Dubai
  


• Release version: 15.1.6
  


• Platform: Salesforce
  


• Chrome Browser, ChromeOS v104.0.5112.110 *

I was changing the Range property on a Dynamic date range from n years ago to n months ago. The input field for n shows a pre-filled value of 1. In order to enter my value of 30, I backspaced over the 1, and the input field vanished.

The same behavior seems to occur on any of the “n” Ranges.

My workaround is to select a different Range, then re-select n years ago, and highlight the 1 before typing 30 over it.

Presumably, this behavior would occur on customer-built pages and not just in the Composer.
