For 5.0.11 I've added a warning banner when attempting to edit binary tiddlers such as PDFs (see the image below).
A big problem with the performance of embedded PDFs is that they are rendered via conversion to a base64 data URI. That means we can hit the browser URL side limit (which I suspect is the cause of the 2MB file problem). The plan is to add support for image tiddlers (including PDFs) to have a "_canonical_uri" which contains the (external) URL of the image. Then when rendering it with [img[myPDFtiddler]] the PDF is referenced remotely via the URL.
