[2.x] Discussion rendering does not allow jumping to the right position #4346
Description
Current Behavior
Since Flarum 1.x Flarum had the weak-point of not being able to calculate sizes of certain elements in posts (such as images). This leads to the effect that if you jump to a certain post (like the last new one) you often are not at the right position as content is loaded.
Comment from @clarkwinkelmann:
The page jumping around on discussion load has become much much worse in Flarum v2. Previously this was only an issue if the posts above the viewport contained images, but now it seems almost every formatting feature (mentions, quotes, GitHub links, ...) causes a shift in the layout after the page was initially loaded.
If I find some time I'll investigate further. As things currently stand this is very annoying and I don't think this should be shipped like this. Either we need to revert back to the v1 behavior, of finally implement proper layout observer and resize so that the scroll never jumps when a post above the viewport changes height.
