Need to upgrade Quill editor or edit code

[ethiwoo]

I used the Quill Editor in momdular-admin-html,
There was a bug displayed as 'tえすと' when entering 'てすと'.
Looking at the current Quill Editor version, it became 1.3.6, which seems to have solved this problem, but I do not know for certain.
I think It is difficult to upgrade Quill Editor in modular-admin-html for me,
so I share some of the source code that I am editting and using.

Here is I referred
slab/quill#1453
https://github.com/azam/quill/commit/c7cc4ca199e6bdf9281c93a4907f581063576851

in vendor.js
・22840 line
Block.defaultChild = 'text';
・29316 line
return document.createTextNode((!value) ? '\u200B' : value);

I think that you need to convert \ u 200 B with a string conversion function.
Thanks.
