ToolbarFlex : The "more-button" adds "tick" icons to menu items that are not selectable

[bthharper]

Describe the bug

After upgrading to ids-enterprise-ng 18.1.3 the header bar that contains the "theme" switcher now adds ticks to items that are not selectable.

See https://stackblitz.com/edit/ids-quick-start-1813-wb3yt6?file=src%2Fapp%2Fapp.component.ts

To Reproduce Steps to reproduce the behavior:

1. Go to https://stackblitz.com/edit/ids-quick-start-1813-wb3yt6?file=src%2Fapp%2Fapp.component.ts
2. Click on '....' on the Header (where the Theme Selector is)
3. Select Help
4. The Help button will now have an erroneous tick on it

Expected behavior

No tick is added to menu items that are not "is-selectable".
