Fix new frames with less or no elements

[mmustra]

Hi @usmanyunusov,

Found an issue when using new frames that either have no elements (during create/update) or have less elements (during update) than previous one.

STR

• No elements: https://stackblitz.com/edit/node-e9sbiw?file=index.js
• Less elements: https://stackblitz.com/edit/node-btwiwm?file=index.js

Solution

• No elements: Will set to default frames. Treating it same as empty string for mark in stop method.
• Less elements: Will set current to 0.
