TightInset in conjunction with "axis image"

According to the documentation, the TightInset axes property is defined as "the distances between the bounds of the Position property and the extent of the surrounding text." In light of this, isn't it wrong for the left-hand TightInset value for the following plot to be zero? Shouldn't it be non-zero to account for the extenf of the yticklabels running along the left-hand side of the axis?

plot(1:5)
title('TITLE');
axis image

TightInset = get(gca,'TightInset')

TightInset = 1×4

0 0.0520 0 0.0526

looks like the

axis image

command makes the space of the ylabels not count for the TightInset in x direction.

the bahvior differs if you add a ylabel instead of adding a title, maybe the reason for the unintuitive behavior is that axis image sets the DataAspectRatio to [1 1 1]
