Comment (by eloquence):

 Here's the procedure I followed:

 1) Per last comment on
 https://trac.torproject.org/projects/tor/ticket/29733 , downloaded 8.0.7b3
 from https://people.torproject.org/~boklm/builds/8.0.7-build3/tor-browser-
 linux64-8.0.7_en-US.tar.xz and ran it

 2) Removed shipped version of NoScript, activated debug mode, downloaded
 Source Code ZIP from
 https://github.com/hackademix/noscript/releases/tag/10.2.2rc3 , and loaded
 its `manifest.json` in debug mode

 3) Changed NoScript settings to these ones: "Sanitize cross-site
 suspicious requests": CHECKED, "Scan uploads for potential cross-site
 attacks": NOT CHECKED, "Ask confirmation for cross-site POST requests
 which could not be scanned": CHECKED

 4) Uploaded a 271M file through source interface of my local SecureDrop
 hardware instance.

 So far so good -- two test uploads succeeded, will do some more testing
 tomorrow. I'll flag this to the OnionShare folks in case they have time to
 do additional testing, as well.

 Thanks for all the help getting this issue resolved. Fingers crossed; will
 post another update after more tests.
