style attribute "column-count" disappears from html.

I have a dynamic page, where one of the elements is a paragraph. I want the text be displayed in 2 columns like in newspaper. If I add 2 sections to the stripe, then I need to split the paragraph into 2 pieces and connect each column to its part of text. But I need that it happens automatically and splits into equal columns. The style attribute Column-count is meant for this, but:

when I add this attribute to the html via code panel it disappears on preview. all styles are there, but column-count does’t exist any more on inspect.

on preview:

I also tried to add simple HTML element and write style tag there. It works from there, but then I can’t connect the HTML element to a collection to make it dynamic.

Any ideas around this?
Thank you in advance!

See the Text documentation for the HTML that is supported.
