After AQUATIC UPDATE,When typing some text on a sign on realm,the text repeat the typing progress again.

Please watch the video clip i uploaded below.

This bug occured when I played on the realm of Minecraft Win10's Edition v1.5.0(AQUATIC UPDATE).It is that when I finished typing in some text on a Sign,it repeatly showed the typing progress again.Which only occured on the realm,If I don't play on the realm,the sign is normal,the text on the sign is firm and stable.But when on the realm,this bug appears.I hope you can try typing some text on a sign on the realm,and you must find the problem! Here I must say the last version of  MC Win10's Editon Realm,this bug doesn't exist.So After the update,the bug appears.This bug is especially unfriendly to the people don't typing in English characters on the signs.
