Blog posts with "flCodeSubs" nodes appearing as unordered lists in RSS

[lmika]

I've used Drummer to write a couple of blog posts that contain nodes with the flCodeSubs attribute set to true. After generating the blog, these nodes display properly as pre-formatted code blocks in the web-browser. However when I view the posts in my RSS feed reader, they show up as unordered lists. I've managed to confirm this by viewing the raw XML of the RSS feed.

Sample post: https://workingset.net/2021/11/15/231218.html?title=iamPermissionsForSsmParametersInMultipleRegions

RSS feed: https://workingset.net/rss.xml (item with guid "https://workingset.net/2021/11/15/231218.html?title=iamPermissionsForSsmParametersInMultipleRegions")

OPML file: http://drummer.scripting.com/_leonmika/blog.opml

Node path within OPML file = /November 2021/November 16/IAM Permissions for SSM Parameters... (sub-node 2 and 4 have the "flCodeSubs" attribute set)
