Print Layout :: Text labels :: Render as HTML :: Bold tags are not shown

[zirneklitis]

What is the bug or the crash?

When the “Render as HTML” for text labels is switched on, the HTML tag <b> is not rendered in the map layout.

Export as image creates a result without the bold weight.

Export as PDF creates a text in the medium or semibold weight rather then bold.

Steps to reproduce the issue

1. Create map layout.
2. Add a text label.
3. Switch on “Render as HTML”.
4. Add text with <b> tag included.

• Actual Results:
  There is no bold text.
• Expected Results:
  The bold text should be rendered.
