RegEx in allow fields

[y-marui]

I have trouble with ignoring specific cases using RegEx.
I tested the two simple rules below.
Both of them are expected to convert AB to XX except AB is a part of ABCD.
(I actuary want to ignore something like /AB(CD|EF|GH)/ but it is just demo rules to simplify the problem.)

But the first rule below also converts ABCD to XXCD.

id: 01FZ7VNZECWHMNE5S9X8T9QSQN
description: ''
expected: XX
patterns: 
  - /AB/i
allows: 
  - /ABCD/
specs: []
tags: []

While the equivalent rule below works correctly.

id: 01FZ7VNZECWHMNE5S9X8T9QSQN
description: ''
expected: XX
patterns: 
  - /AB/i
allows: 
  - ABCD
specs: []
tags: []

The problem may occur only if one uses the RegEx in the allows field.

My environment is as follows.
macOS 12.2.1
node v17.8.0
npm 8.5.5
@proofdict/textlint-rule-proofdict@3.1.2
