Custom tags are not displayed in the taglist

Known Issues
#1

Hi! Custom tags added manually in the tag list field are not visible in that field after the page is refreshed.

Here is my field definition:

    classes:
        label: Classes
        type: taglist
        separator: comma
        mode: array
        customTags: true
        useKey: true
        options:
            bg01: Background color 1
            bg02: Background color 2
            bg03: Background color 3

I added a test tag:

After saving, I see the tag in the code:
sections[10][classes][] = "test"

However, after reloading the page, the tag is no longer visible in the field. So, after saving other changes, the tag will be removed from the code.

I know it is related to the useKey option, but if there is no label, can the key be treated as a label?

Hey @Radek !

There is actually code in v4 to address this scenario since it is problematic for integer keys.

// Keys cannot be used with custom tags
if ($this->customTags) {
    $this->useKey = false;
}

However you have highlighted a legitmate use case for it.
