Issue Summary

Resizing the width for Fixed Width Table is limited by the text length in the table

This is reproducible on Data Center: Yes

Steps to Reproduce

1. Install Confluence
2. Create a new page and insert a 3x3 table
3. Change the table width to Fixed Width
4. Adjust the width of any column to any specific length
5. In the column that has the width adjusted, insert a long string in one of the column with only alphanumeric without any space (so that it exceeds the column length)
   example

   123456789123456789123456789123456789
   

Expected Results

The "fixed width" of the column should restrict the inserted text and force it into the next line
Table Width Resize 7.4.mp4
Confluence 7.13 and before is not impacted by this behavior

Actual Results

The inserted long string of text extends the set column width, as well as restricting the column width to be adjusted to smaller than the string length
Table Width Resize 7.19.mp4
Confluence 7.14.0 and above is impacted by this behavior

Workaround

Install Confluence Source Editor to edit the page and change the table class from fixed-width to fixed-table (which is what was used in the older Confluence versions):

<table class="fixed-width" style="width: 92.0px;">
  <colgroup>
    <col style="width: 91.0px;"/>
  </colgroup>
  <tbody>
    <tr>
      <td>123123123</td>
    </tr>
  </tbody>
</table>

<table class="fixed-table" style="width: 92.0px;">
  <colgroup>
    <col style="width: 91.0px;"/>
  </colgroup>
  <tbody>
    <tr>
      <td>123123123</td>
    </tr>
  </tbody>
</table>
