[bug]: Toast does not close/vanish on click on closing-x

Steps to reproduce the behavior:

Let any dismissible toast show up, and try to close it manually.

Expected behavior
The toast should vanish.

Desktop (please complete the following information):

• OS: Windows 10
• Browser -> all browsers (chrome, edge, firefox, opera)
• Version (current versions at 14.12.2024)

Additional context
Should we implement a close functionality on click/keyboard-enter by ourselves for each occurence of a toast, or would you do that once centraly in your component for all occurences?
