Describe the bug

Using the 'sort-compare-options' prop in conjunction with a v-model on B-Table causes chrome to crash/become unresponsive. The only way to exit the web page is to kill the tab process.

Steps to reproduce the bug

1. Go to https://codepen.io/trickster223/pen/bGEbBYP
2. Add v-model="model" to the b-table component
3. Codepen output will become blank, browser page will lock up, table never gets rendered.

Expected behavior

Table renders with sorting options applied and v-model available for a list of read-only data.
