Issue Summary

In some cases, table alignments get changed after converting legacy editor pages into the new editor.

The values in the data-layout attribute of the table sometimes return "default" or "align-start".

The issue is inconsistent and happens to tables with identical structures without any prior configuration like the below example:

<table class="wrapped"><colgroup><col /><col /></colgroup>
<tbody>
<tr>
<th>Test</th>
<th>Test</th></tr>
<tr>
<td>

Steps to Reproduce

1. Convert a legacy editor page that contains multiple tables into the new editor

Expected Results

Table layout gets preserved

Actual Results

Table layout is sometimes changed to "default" or "align-start"

Workaround

Realign the tables manually after the conversion
