when I click on the country, the console output Cannot read properties of null (reading 'tagName')

[wang3616359git]

In Vue2.5.17, when I click on the country, the console displays the following content
Core. js? V=2fe6d2f: 1 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'tagName')
This is the version I am using "vue tel input": "^ 5.14.2"
The component can be rendered and the values can also be bound, but there is no country code. When I click on the country, it does not work and the console reports an error
