showFlag layout issue in Forge when omitting title (icon on different line)

Hi everyone,
I’m using showFlag from @forge/bridge to show a success message in a Forge app like this:

setTimeout(() => {
    showFlag({
        id: 'save-success',
        description: 'string',
        type: 'success',
        isAutoDismiss: true,
    });
}, 1500);

However, when I omit the title, the success icon appears on a separate line above the description.
This makes the flag look inconsistent and awkward compared to AP.flag.create() in Connect, which displays the icon and text inline — even with no title.

I’ve tried setting title: “” or title: ‘\u00A0’ => no change

Expected: If no title is provided, I’d expect the icon and description to stay on the same line, just like AP.flag.create().
My setup:
Forge Bridge version: 4.1.0, I’ve tried upgrade it to 5.0, still did not work.

Is this a known issue with showFlag, or is there a recommended way to keep the layout inline without using a title?

Thanks in advance!
