CSS3 tab-size is supported in all other browsers, and defines how many spaces the tab character should consist of.
The tab-size property is now on the Microsoft Edge backlog with a priority of medium. You can track status updates at https://developer.microsoft.com/en-us/microsoft-edge/platform/status/csstabsizeproperty/

Building a code editor that works on Edge is going to remain pretty painful until this exists. Would be great to see something happen here.
Three (3) years down the line, still not supported. Is there a reason against? How long could it possibly take for implementation?
Please do something now; we don't want/need another "Internet Explorer".
All the other browsers have already implemented it, so what's the delay?
At least make the default width 4 spaces in the meantime. Eight is just obscene.

Why is this taking so **** long? It says "Under Consideration", but there's nothing to consider. It's part of the official W3 specification. FIX THIS ALREADY.
