I utterly tested to rewind my issue and I failed to replicate it as well. Before posting I was able to replicate it with any item on my inbox.
I am sorry for issuing a non existing issue, Sir. Thank you for your careful exploration and documentation.
To clean my name I post an other (little) todo:
If a comment posts a picture (of a certain size?) we are unable to reply since long-pressing the comment does not expand the comment but opens the context menu for further actions on the image.
See the reply to this comment as an example:

Just to let you know:
Your work contributes to society.
// Edit: we do not have any handle around the picture to refer to the comment as it when long pressing. I expected to enlarge the comment when long pressing the header of the comment where no text is shown.
Right and above to the picture but left to the hide/show arrow.
When writing this, it appears we have three states and my terminology is wrong but I am unable to adapt yours ;)
