`eager: true` break the mask

[Sébastien LeBlanc]

Describe the bug

Be this mask:

telMask: {
    mask: (val) => (val.startsWith('1') ? '1 (###) ###-####' : '(###) ###-####'),
    eager: true,
},

Typing 1 should results in 1 ( but results in 1 (1
Then, if you type a full mask, you can't delete !

[Sébastien LeBlanc]

The mask break when you try to delete any caracter that was added by eager: true.
Another exemple where I added eager: true so that the space would be automatically added.

Be this mask:

postalMask: {
    mask: '@#@ #@#',
    eager: true,
    tokens: {
        '@': { pattern: /[a-zA-Z]/, transform: (chr) => chr.toUpperCase() },
    },
},

Should be fixed in v2.1.7
