Div change height when user clicks JS content

I have a problem with increasing div element height. To see this problem, you need to insert a new "field for error case" element . Then you need to click the top right div / top left div . You can type 1 letter and then delete it (or just set the focus and delete it) → you can see the div element increasing. I do not understand why this is happening. Sorry for my bad english. Thanks!

I also notice that this happens if you do not comment innerDiv1.setAttribute("data-text", "Full Name of the Case");

The problem occurs in the Safari browser.

[contentEditable=true]:empty:not(:focus):before {
    content:attr(data-text)
}
.boxed {
    margin: 5px;
    border: 2px solid black;
    max-width: calc(100% - 10px);
}

.inline {
    display: inline-block;
    vertical-align: middle;
    max-width: calc(100% - 10px);
}
.divTable {
    display: table;
    border-collapse: separate;
    border-spacing: 5px;
}
.divRow {
    display:table-row;
}
.divCell {
    display:table-cell;
    border: 2px solid black;
}
<script>
    function insert(elem) {
        document.getElementById("mainDiv").focus();
        var sel = window.getSelection();
        var range = sel.getRangeAt(0);

        range.insertNode(elem);
    }

    function legalCaseBox() {
        var innerDiv1 = document.createElement('div');
        innerDiv1.contentEditable = 'true';
        innerDiv1.style.minWidth = '50pt';
        innerDiv1.style.minHeight = '50pt';
        innerDiv1.classList.add('divCell');
       //innerDiv1.setAttribute("data-text", "Full Name of the Case");

        var innerDiv2 = document.createElement('div');
        innerDiv2.contentEditable = 'true';
        innerDiv2.style.minWidth = '50pt';
        innerDiv2.style.minHeight = '50pt';
        innerDiv2.classList.add('divCell');
        innerDiv2.setAttribute("data-text", "Year");

        var firstDiv = document.createElement('div');
        firstDiv.contentEditable = 'false';
        firstDiv.classList.add('divTable');

        var rowDiv = document.createElement('div');
        rowDiv.classList.add('divRow');
        rowDiv.appendChild(innerDiv1);
        rowDiv.appendChild(innerDiv2);

        firstDiv.appendChild(rowDiv);

        var secondDiv = document.createElement('div');
        secondDiv.style.minWidth = '150pt';
        secondDiv.style.minHeight = '80pt';
        secondDiv.contentEditable = 'true';
        secondDiv.classList.add('boxed');
        secondDiv.setAttribute("data-text", "Case summary");

        var div = document.createElement('div');
        div.contentEditable = 'false';
        div.classList.add('inline');
        div.classList.add('boxed');
        div.appendChild(firstDiv);
        div.appendChild(secondDiv);

        insert(div);
    }
