Selection.addRange() error in bootstrap3-wysihtml5-custom.js

Hi @zorz, how are you doing?
Can you please, help to fix the error mentioned above?
My theme / site is running so smooth now that this only one error is driving me crazy.
Another question is when reCaptcha v3 will be compatible with Arcane?
Enabling it on bestweb plugin does not show the reCaptcha badge on bottom page, which indicates that reCaptcha is not working properly.

Thanks in advance!
