Text2d Aabb aren't in the right place and can get culled when they shouldn't #20145
Description
Bevy version
0294fa8 (main @ 15th July '25)
What you did
Placing text with a large TextBounds, intending that the bounds shows the maximum size the text should take up, even though the current text is small and fits easily inside.
What went wrong
Text isn't rendered, because the computed Aabb is off screen and gets culled.
Additional information
Seems to be caused by this earlier fix: #17365
If I don't specify TextBounds, or I disable calculate_bounds_text2d, or the text is sized and located such that the Aabb is within the screen, then the text is rendered as expected.
I have updated the example from #17365 for current Bevy, also to show the text bounds and calculated Aabb's, which are way off where the text is.
I tried fixing it by simply disregarding TextBounds in the Aabb computation, but I suspect that breaks what this previous change was trying to fix!
