Originally assigned to: @profvjreddi on GitHub.

when clicking the pdf view on the website, and copying test to paste into google, it copies gibberish rather than the desired selected text.

for example: the following copies as 4PNF DPNQJMFST HP CFZPOE TUBUJD LFSOFM TFMFDUJPO (reproducible elsewhere)

This seems to be an issue that occurs only when the book is viewed via the web browser on Chrome.

It doesn't seem to happen if we download the PDF and open it in a regular PDF reader.
