:line-nums | Invalid array length

[l99shka]

                <CodeEditor
                    class="border"
                    v-model="code"
                    :languages="[['php', 'PHP']]"
                    theme="a11y-light"
                    font-size="14px"
                    width="100%"
                    height="140px"
                    border-radius="0"
                    :line-nums="true"
                />

if I use the editor inside the collapse, then after opening I will have an error:

How to fix it?

I have the same problem,, I changed the v-show to v-if, and it was solved, maybe it was the loading order problem?

The issue is that this.lineNum can get set to a NaN value, because heightNum calculates to NaN if singleLineHeight is zero:
