Until AI 28, when exporting an SVG with soft carriage returns (shift-return in Illustrator), text was not converted to outlines.

With Illustrator 28, Adobe significantly changed the format of exported SVGs.

Now, when exporting an SVG with Font Type: SVG, using a soft carriage return (shift return) in Illustrator causes the text to be converted to outlines.

If I create a simple AI file containing only the text "test file", here is the resulting SVG code:

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 500 500">
<defs>
<style>
.cls-1 {
fill: #3e3e3e;
font-family: ArialMT, Arial;
font-size: 19px;
}
</style>
</defs>
<text class="cls-1" transform="translate(58.5 71.5)"><tspan x="0" y="0">test file</tspan></text>
</svg>

If I add a single soft return between the two words, I get an alert "The following items could not be exported properly / Text is converted to outline"

the result is an SVG file that is five times bigger:

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="0 0 500 500">
<defs>
<style>
.cls-1 {
fill: #3e3e3e;
stroke-width: 0px;
}

I have tried saving as a copy, exporting for web, exporting via JSX with both exportFile using ExportType.WOSVG and ExportType.SVG.

Is there any way to export an SVG that won't cause text with soft returns to be converted to outline?
