[Bug]: Only a single icon can appear at a time when adding to the Tab Bar

[tobalsan]

Describe the bug

Obsidian v 1.6.7 Commander v0.5.2

I added multiple items for the Tab Bar in Commander configuration, but no matter how many items I add, there's only a single that ever appears.

Relevant errors (if available)

enhance.js:1 Uncaught DOMException: Failed to execute 'add' on 'DOMTokenList': The token provided ('obsidian-excalidraw-plugin:Downloaded/Box Selected Elements') contains HTML space characters, which are not valid in tokens.

For each command added to the tab bar, an icon should appear.
