Negative floats get highlighted in different color

[tom-programming]

MWE:

(module
(func (result f64)
  f64.const -8.33
  f64.const 8.33
)
)

see my output:

VSCode version: 1.58.0
OS: macOS
Extension 1.3.1

EDIT: more specifically the "-8" gets lexed as an integer and ".33" is invalid. It is probably an issue of priorities. Moreover the keywords "get_local" and "set_local" show up as "invalid" too.
