Bug report

Bug summary

Texts outside of the axes extents interact "interestingly" with constrained_layout.

Code for reproduction

ax = figure(constrained_layout=True).add_subplot(); ax.plot([0, 1]); ax.text(2, 2, "hello")
ax = figure(constrained_layout=True).add_subplot(); ax.plot([0, 1]); ax.text(4, 4, "hello")

Actual outcome

The first example gives

the second one

together with (only for the second one)

UserWarning: constrained_layout not applied because axes sizes collapsed to zero.  Try making figure larger or axes decorations smaller.

(You can also try to pan the axes and get interesting results in that way.)

Expected outcome

I'm not actually sure how I'd actually want constrained_layout to handle such cases, but the current state seems... shaky.
