When log in to wikipedia the new jquery.placeholder.js (gerrit 98137) is used on Special:UserLogin. When the cpu is high, and the username is typed and than with tab the password field is selected and the password is typed, sometimes the first letters of the password are missing.
Sometimes the whole placeholder text is select and will stay in the input box.
Please revert or fix the new jquery.placeholder.js. Thanks.
