I cannot get the warning, an you provide a minimal example?

There is no way to configure the width of the tooltip, see microsoft/vscode#14165

Hence, we cannot do much about how the message gets wrapped. So far, all lines of a message are joined and then wrapped in the tooltip. The best we can do is to honor line breaks from the original message.

@jlelong honoring the newlines is all I asked for, thanks.

@jlelong

Newlines are fine now, but aren't these boundaries a little too big? (they look like tabs and I think they're meant to be spaces)

[jlelong]

Unfortunately, the boundaries are are coded by the package itself using \ClassWarning which repeatedly calls \@spaces defined as 4 spaces in latex.ltx.
I think we cannot do much about it.
