Changing font styling causes text to move upwards on the page

Issue type

UX/interaction

Description with steps to reproduce

Changing font styling causes text to move upwards on the page while the input field is active.

Adjusting other parameters (such as text justification or font size) or closing the input field causes the text to return to the expected position.

This also happens when adjusting styling from the properties panel, after which a relayout causes the text to return to the expected position.
