Focus toggling on click in Svelte Component

I made a component for entering financial numbers, to be used in my input forms. It works really great now, except for one odd behavior: When I click on the input field it gets the focus as expected, however when clicking on it when it already has the focus takes away the focus.

There's only one on:click handler in the component and when I removed it the behavior didn't change. So, I don't know what's causing this oddity.

<p>Input with precision=2 <Money id=first bind:value=a precision=2/>
    <br/>Value={a}</p>
<hr/>
<p>Input with no precision specified <Money ref:m2 bind:value=b/><br/>
    Value={b}</p>


<script>

    export default {
        data(){return {
            a:1234.34,
            b:3.14159265
        }},

        components: {
            Money : "./Money.html"
        }
  }
</script>

<style>
    /* How to sytle the component*/
    :global(#first) {
        font-family:serif;
        lobal(#first) {
        font-family:serif;
        background:#ff9;
    }
</style>

Here's the REPL that shows the issue.
