I instead use <div class=“flex”><\div> now.

If the class name is not enough for me to guess, I just hover the class name and the LSP will show me the applied styles.

Another issue is that Shopify changes the name of these components for no reason, for example InlineStack was once called Inline, then HorizontalStack, then InlineStack, while the flex box model hasn’t change since 2012
