Ligature "=>" isn't displayed correctly

[pacmancoder]

I found interesting font Fira Code with ligatures, but I found that ligature for operator "=>" is not displayed correctly. So, I tried to fix this. I was getting correct ligature if I changed 'match' for operators section form this:

# Operators
{
  'comment': 'Operator'
  'name': 'keyword.operator.rust'
  'match': '(\\+|-|/|\\*|=|<=|>=|\\^|&|\\||!|%|::|\\bas\\b|<<|>>|>|<)'
}

to this (added |=>| ):

# Operators (Good)
{
  'comment': 'Operator'
  'name': 'keyword.operator.rust'
  'match': '(\\+|-|/|\\*|=>|=|<=|>=|\\^|&|\\||!|%|::|\\bas\\b|<<|>>|>|<)'
}

Correct	Incorrect

So, is my fix correct?
(Sorry for my poor English)

It should be correct. It is however a duplicate of #59.

This should be fixed in #59
