Text area field which is using markdown editor is not working within field group

Problem/Motivation

Not able to add or edit the content in the text area field which is configured markdown editor when text area field added into field group using field group module. It is working fine without using field group.

Steps to reproduce

Step 1: Create a new content type and add a text area field. Select full html text format and configure markdown editor for text area field.
Step 2: Install Field group module.
Step 3: Go to Manage form display and add a new field group and configure its widget as "Details" and disable "Display element open by default" option. Then add that text area field into the field group.
Step 4: Save the changes.
Step 5: Create a content from new content type with field group which has text area field. By default, text area field is hidden and it opens when click on the label of the field group. I can't able to add or edit the content in the text area field as cursor is not pointing to the field.
Step 6: I'm able to add content into text area field if it is not added into the field group.
