vscode: built in editor.action.selectToBracket breaks in TOML files

[bhainesva]

The behavior of vscode's built in editor.action.selectToBracket command changes when used in a TOML file, specifically it seems to ignore curly brackets.

For example in a file with the following text, where | represents the cursor:

name = { first = "To|m", last = "Preston-Werner" }

If the language of the file is set to "Plain Text", running editor.action.selectToBracket will cause first = "To|m", last = "Preston-Werner" to be selected. If the same thing is done after changing the language mode to TOML no text is selected.

It's possible this is a bug with vscode itself, but I've only seen it happen in TOML files so decided to start here, apologies if I'm the wrong place.
