Unexpected interaction of colorbar handle with tiledlayout in v3.42 commit

[mahendraK96]

The fix for the colorbar title works in figure environment but gives errors when used together with tiledlayout. MWE below

[X,Y,Z] = peaks;
F = figure;
T = tiledlayout(F,1,2)
ax1=nexttile(T,1);
contour(ax1,X,Y,Z,20);
cb1 = colorbar;
ax2=nexttile(T,2);
contour(ax2,X,Y,Z,10);
cb2 = colorbar;
title(cb1,'Tst','FontSize',18);
title(cb2,'Tst','FontSize',18);
export_fig(F,'Tst','-pdf','-png','-transparent');

Error Message: Error using getappdata Value must be a handle.
