Label alignment issues when HTML formatting is enabled #50887

Open Sidapo opened 1 year ago

Sidapo commented 1 year ago

(edited to include further information)

What is the bug or the crash?

When HTML formatting is enabled & the label font size is set by a data defined override: Using <p> to break a line causes text alignment issues for all alignment types except Left. For example, this label is set to Right: image

Steps to reproduce the issue

  1. Enable HTML Formatting
  2. Enter a label value with <p> to create a line break
  3. Set the label font size by a data defined override (just setting a number is sufficient)
  4. Change label alignment to anything other than Left

It seems to be related to my project somehow: When I drag the layers (incl. the style) to a new QGIS instance it renders the labels as expected. There are multiple layers that behave as described above in the QGIS project.

I think I found what triggers the bug: The misalignment occurs when a data defined override is set for the label size.

I confirm this bug. Incorrect label alignment and label background size when an expression is used to define text size. Снимок экрана_2022-11-25_15-24-21

Also, wrong alignment also appears in the map composer in the Text element.

The issue is still actual in 3.28.1
