Tidy HTML formatting in Gutenberg HTML blocks

When forming my own HTML blocks, trying to keep my HTML tidy for easy debugging purposes is a pain because tab spacing cannot be used, and therefore multiples of 4 spaces or more has to be used for each indentation level. Having to count 1,2,3,4…1,2,3,4…1,2,3,4 for example to keep everything in line slows down page production too.

Is there a way of allowing tab spacing to be used within Gutenberg blocks?
