copy and paste link shown there is fine, and if we copy it from starting selecting from outside of its container it will copy the url correctly, but as normal in Gmail for android if we click it its copying a mispelled url.

something like this one

https://mobile-webview.gmail.com/-*0*******9/**211***********56#m_-*#######714######1_

i replaced some digits from the above link with *s and #s, which was not necessary, but i had to.
