Toast doesn't show the saved message when reopened

Wappler Version : 6.5.4
Operating System : MacOS
Server Model: NodeJS
Database Type: MySQL
Hosting Type: Docker

Expected behavior

What do you think should happen?

The message text under the Toast Properties should display correctly when reopened after saving the selection action.

Actual behavior

What actually happens?

The text is saved, and it appears correctly in the code. But when the same action (in this case: dmx-on:success) is reopened, the message text disappears under the Toast Properties, and it will not let the action be saved without re-adding the message text.

Update: If only text or a data field are selected, the message appears correctly when reopened. It's only an issue when data field is combined with text. I have included an example when it doesn't display the message.

dmx-on:success="{message:'bookmarked'?'The item has been bookmarked!':'The bookmark has been removed!', title: 'Bookmark Status', icon: 'fa-regular fa-bookmark fa-fw'})"

A workaround could be to use inline flow.
Add a condition and set toast step in both then & else separately.
I have been trying to avoid inline ternary expressions since flows were added.

I see, that could be the issue. I will try this with an inline flow.
