disable placeholder from auto-resizing

[oreporan]

If the placeholder is too long, it creates a newline, even when I put ellipsis on it, it creates the 3 dots but still the height of the textarea expands.

 flex-grow: 1;
    padding: 0 0 0 10px;
    border-width: 0;
    resize: none;
    line-height: 20px;
    margin-top: 14px;
    margin-bottom: 14px;
    &:focus {
        outline-width: 0;
    };
    &::placeholder {
        text-overflow: ellipsis;
    };
