What happened?

Tabs are rendered as → (which takes up 2 spaces) and as 4 spaces for lines that are just context. In the screenshot, see that line 4 in the biome check output is showing as being vertically aligned with line 5, even though line 5 has 2 tabs while line 4 has 1 tab.

This can be reproduced with a single biome.jsonc file and having it check itself for formatting
biome check ./biome.jsonc

// biome.jsonc
{
	"$schema": "https://biomejs.dev/schemas/1.9.4/schema.json",
	"json": {
		"formatter": { "trailingCommas": "all" }
	}
}

Expected result

I'd expect the context line tabs to be 2 spaces instead of 4
