ui-mask="1.1.9.999" error

[ivaldo]

When trying to set the start "1.2.3.4.5", using the mask "1.2.3.4.5.9.999", for example, the input does not accept the entered value, automatically prepending with a random digit.

package.json -> angular-ui-mask": "^1.8.7"
sample code: <input type="text" ng-model="field" ui-mask="1.1.9.999">
