Magento 2 - How to keep those checkout error messages from disappearing

If you ever had an error during checkout, you might have noticed that the error message hides after a few seconds. It's five seconds to be exact. That's too quick for me. Many times I don't notice it until it disappears.

Why hide it at all? I think it's best to keep it visible until the customer decides to hide it. Here's how to accomplish that:

First, copy this file:

Over to:

Then change this line:
<div data-role="checkout-messages" class="messages" data-bind="visible: isVisible(), click: removeAll">

<div data-role="checkout-messages" class="messages" data-bind="click: removeAll">

Clear your cache and re-deploy the static content:
bin/magento setup:upgrade
bin/magento setup:static-content:deploy

There you have it. This will keep the message visible until the customer clicks on it.

How does this work?
The "visible: isVisible()" part tells the component to trigger a timer when the error message becomes visible. You can see this in:
 * Checks visibility.
 * @return {Boolean}
isVisible: function () {
    return this.isHidden(this.messageContainer.hasMessages());
defaults: {
    template: 'Magento_Ui/messages',
    selector: '[data-role=checkout-messages]',
    isHidden: false,
    listens: {
        isHidden: 'onHiddenChange'
This watches for any error messages that might load, and to call onHiddenChange() when that happens:
onHiddenChange: function (isHidden) {
    var self = this;

    // Hide message block if needed
    if (isHidden) {
        setTimeout(function () {
            $(self.selector).hide('blind', {}, 500);
        }, 5000);
This tells it to hide the error message after 5000 milliseconds.

The choice to use "isHidden" as the variable name is a bit confusing. When the message container has messages, isHidden is set to true. That sounds backwards to me. Basically, isHidden acts like a switch. It's initially set to false by default, and then gets set to true when there are messages, triggering the hide timer in onHiddenChange.
