Creating an option list for a cascading field where a child has the value of its parent id causes the basic mode to use that value as an id in a search.

Problem

Creating an option list for a cascading field where a child has the value of its parent id causes the basic mode to use that id as a value in a search.

Environment

Jira server 8.13.14

Steps to Reproduce

1. Create or select a custom field of type "Select List (Cascading)", out of the box Operational categorization.
2. In the database search for the id of the Parent for the options, for example:  "Server Change", id = 10076.
3. Now edit the options for Server Change and add a child with value 10076.
4. Run reindex
5. Go to search issues, select > more > Operational categorization with values;
   • Parent: Server Change
   • Child: 10076
6. Click update

Expected Results

The search with the set values will be used to search issues.

Actual Results

A message is shown that the search was invalid:

The option '10076' specified in function 'cascadeOption' is not a valid parent option.

Workaround

Switch to advanced search or add a space character behind the child option value in the field configuration.
