ISSUE: The HTML page output that was generated "correctly" in v12.3 no longer works in v13. Specifically, the "Column" format of a simple List is now lost when the HTML page is generated.
The following code worked beautifully in v12.3:
myVar = {"a", "b", "c", "d", "e"};
htmlPage = ExportString[Column[myVar], "HTMLFragment"];
Export["columnFails.html", StringJoin["<html><body>",
"<p><h1><center>Page Heading</h1></p>",
"<p><center>",
htmlPage, "</body></html>"], "Text"];
The output was an HTML Page as shown here (with {a,b,c,d,e} in the correct vertical Column format):

In v13, I now get:

Can anyone advise why this is occurring and/or how to fix this in v13 please? Any thoughts on an alternative approach would be much appreciated as well - thankyou.
Many thanks in advance.
