Fix invisible button when used on desktop

Problem/Motivation

Hi guys, you have made a great module. Thank you very much.
However, the icon for opening the selection dialogue for the social networks on which your content is to be shared is only displayed on the desktop if there is at least one character in the title of the block.

The module is great for placing in the Social Bar region of Olivero. At the moment, however, you have to put an invisible ascii character such as &zwnj in the block title so that the button is also displayed on the desktop and, for example, displays the share dialogue under Windows 11. It would be very nice if you could fix this small issue so that the module can also be used on the desktop by “ ordinary people”.

Many thanks.

Steps to reproduce

Install Drupal CMS
Install the Module as usual
Add a Block to the social Share sidebar
Hide block Title

See button is gone

Enable the block title and see that the button is visible now.

Change blocktitle by just setting an invisible ASCII sign as the title of the block
Now you see how it should look if you view it in desktop mode.

Proposed resolution

fix code so that icon still showing when block title is hidden.

Remaining tasks

write a path

User interface changes

Trigger-Button will be shown on the Desktop as well.

API changes

none

Data model changes

TBD
