Show more/show less: text width changes, causing reflow

[texttheater]

Detailed description

When using the "show more" button to unfold a long toot, text reflows across the whole post body. It seems that the available text width is greater when unfolded, so lines become longer. As a result, I have to find back my reading position after tapping "show more".

The expected behavior would be that all lines but the last one (which is shortened) flow exactly as in the folded toot.

The buggy behavior can be observed in the attached screenshots. Note that the second line of text in the toot body is already different, ending in "means" when folded but in "means to" when unfolded.
