Ionic 4 - ion-input style not loaded for the first time

Hi guys,
I have a problem with the tag .
I put the style but it does not loaded for the first time on the Browser/Mobile device.
The style applies just when i refresh the page for the browser case
But for the mobile we can not do that :tired_face:

My code SCSS

ion-content {
    --background: var(--ion-color-bg-gray);

    .form {
        padding: 10px;
        padding-bottom: 400px;
        .list {
            border-radius: 5px;
            margin-bottom: 0px;
            .item {
                --border-color: var(--ion-color-bg-gray);
                --padding-top: 4px;
                --padding-bottom: 4px;
                font-size: 14px;
                ion-input {
                    text-align: right;
                    --padding-end: 0;
                    --padding-bottom: 10px;
                    --padding-top: 10px;

                    --background: var(--ion-color-success);
                    --color: #fff;

The result.
