Unable to open office URIs

[Kenzeno]

Hello,

Since the last version 1.14.1077.41 (Stable channel) (32-bit), I'm unable to open office URIs.
For example an Excel URI starts like this: ms-excel:ms-excel:ofe|ofc|u|https://mywebsite.com/myexcel.xlsx

Instead of the file opens in Excel, I'm getting an error that the site cannot be reached:
This site can’t be reached
The webpage at ms-excel:ofe%7Cofc%7Cu%7Chttps://mywebsite.com/myexcel.xlsx might be temporarily down or it may have moved permanently to a new web address.
ERR_UNKNOWN_URL_SCHEME

A already reported unfixed bug, happens with other URIs (except schemes http and https), too.
