[Bug]: Constrained layout UserWarning even when False

Bug summary

When using layout settings such as plt.subplots_adjust or bbox_inches='tight, a UserWarning is produced due to incompatibility with constrained_layout, even if constrained_layout = False. This was not the case in previous versions.

Code for reproduction

import matplotlib.pyplot as plt
import numpy as np
a = np.linspace(0,2*np.pi,100)
b = np.sin(a)
c = np.cos(a)
fig,ax = plt.subplots(1,2,figsize=(8,2),constrained_layout=False)
ax[0].plot(a,b)
ax[1].plot(a,c)
plt.subplots_adjust(wspace=0)

Actual outcome

The plot works fine but the warning is generated

/var/folders/ss/pfgdfm2x7_s4cyw2v0b_t7q80000gn/T/ipykernel_76923/4170965423.py:7: UserWarning: This figure was using a layout engine that is incompatible with subplots_adjust and/or tight_layout; not calling subplots_adjust. plt.subplots_adjust(wspace=0)

Expected outcome

no warning

Additional information

Warning disappears when constrained_layout=False is removed
