Dear Team,

After upgrading Jenkins to the latest LTS version 2.263.1 the HTML put in job description, or build description is somehow processed server side and stuff is removed, like:

1. "font" tags are removed completely
   • IMPACT:   lost all formatting (color, font size, font effects)
   • workarround is to set the font as a style  
     • source:           <li><font size="2" color="purple"> MESSAGE </font></li>
     • rendered:        <li> MESSAGE </li>
     • solution:          <li style="color:purple!important; font-size:20px"> MESSAGE </li>
2. "title" attributes are removed from all tags
   • IMPACT:   no more tooltips on our tables
   • No workaround
     • source:         <td title="TOOLTIP"> MESSAGE </td>
     • rendered:      <td> MESSAGE </td>
3. "rowspan" / "colspan" attributes are removed from "td" and "th" tags
   • IMPACT:   pre-existent tables are now misaligned 
   • No workaround
     • source:        <th rowspan="2" colspan="3">Build</th>
     • rendered:     <th>Build</th>
