Web IDE does not work nicely wtih IMEs - input get duplicated

I tried to type Malayalam in to the editor, using FCITX input method in Linux, used Swanalekha input method for Malayalam(All comes with Debian or Ubuntu. Can give specific installation instructions if required).

Following screenshots shows every letter getting repeated:
