Spoilers don't obscure text in PDF export

[jack5github]

Obsidian's in-built 'Export to PDF...' function covers spoilered text with the expected black rectangles, however the underlying text can be extracted by copying the affected line and pasting it elsewhere. It would be great if this plugin had a setting that could handle when document text is exported, offering 3 options: Spoiler (allow copying), Obscure (replace spoilered characters with a symbol, perhaps █?) and Reveal (don't spoiler).
