MineMdoesd the same. Been happening for a couple ofoweeks on my Samsung with SwiftKey, no other sites/apps are affected
Try the spanner icon on the top right of the text box and see if it still happens. You will have to input everything by hand (= learn BBCode), but also get rid of any possible "helps that don't help". If it doesn't happen there, we know the JS based editor is the culprit. Here (normal computer) the rich text editor has the bad habit of moving the cursor to the end after selecting and cutting some text. "ABC", select and cut A, then cursor goes after the C instead of staying before the B as in any other program. Other times is shows lag while doing normal things.
I'm typing this using the spanner icon and it seems to have rectified the issue, looks like the standard editor is being too helpful for it's own good. Looks like javascript is the issue, surprising no-one.
Default android keyboard seems less affected by the glitch, but using SwiftKey in the simple text editor and just switching back to post links seems to be the best option for a work around.
