Curved labels disappear when rendering across multiple vertices

Curved labels disappear when trying to render across multiple vertices (or line segments) along a line. It is as if the rendering engine treats each line segment as an individual feature, essentially ignoring the previous and next segments, resulting in labels only showing when zoomed in enough to have one segment span the width of the label to be rendered.
When I increase the inside and outside angles, the issue is not solved. Instead, the label almost seems to get cut off at the end of the segment, resulting in oddly rotated individual characters sparsely appearing.
This issue did occur in version 2.x, nor does it occur (I think) in projects that I created in version 2.x; it only seems to happen when I create a project in version 3.x. I first noticed the issue in version 3.0 but because of my laziness, I haven't reported it until now.
