Tabs don't get replaced with spaces in snippet transformations

• VSCode Version: 1.47.3 (system setup)
• OS Version: Windows_NT x64 10.0.18362

Steps to Reproduce:

1. Create a snippet with a transformation which replaces part of the text with tabs, e.g. the following Python snippet

	"Plain object": {
		"prefix": ["class"],
		"body": [
			"class ${1:Name}:",
			"\tdef __init__(self, ${2:arg_list}):",
			"\t\t${2/ *([^:]+?) *(:[^,]+)? *(,|$)/self.${1} = ${1}\n\t\t/g}",
			"\tdef __repr__(self):",
			"\t\treturn repr(self.__dict__)",
			""
		]
	}

2. Use the snippet. The explicit tabs at the beginning of lines get replaced with spaces per the file preferences. However, the tabs that result from the transform don't overgo the same process.
