Research direction

Start by reproducing the warning with MarkdownPreview, then compare the behavior when the code importing or using MarkdownPreview is removed. Trace the generated source-map warning to determine its cause; done means the warning no longer appears when MarkdownPreview is used.

Description

Hello,

I started to see this odd warning after using MarkdownPreview (i.e., if I commented out the code that imports/uses MarkdownPreview the warning disappears). Any idea?

Many thanks in advance!
