App Structure doesn't display columns when class has space

Wappler Version : 3.3.2 FW7 v5 Core
Operating System : mac

Expected behavior

Column will be displayed in the App Structure panel even if the class attribute has a space ( such as when other classes are added along with ‘col’ )

Actual behavior

The column disappears from the App Structure

How to reproduce

Correct display:

Add second class - lose column:

Just add a space - lose column:

Is this only on FW7 or does it happen on bs4 projects as well?

Maybe it is just a refresh issue? Does it gets fixed after a file same or app structure refresh?

What if you add the space from an inspector?

I don’t know if it happens on bootstrap.

Refreshes and Wappler restarts do not change anything.

I’m added these within the Code view.
