[BUG] Auto-resize does not work with 'center' text alignment

[Ulugbeg]

Repro steps:

• ensure auto-resize is enabled.
• add a new node to a canvas
• ensure text alignment is center
• ensure auto-resize is enabled for the node
• add multiple lines to the node so the node extends downwards
• exit the node by clicking on the canvas.
• observe the node is now resized to the original, minimal size, not displaying all the entered text.
• change the text-alignment to either left or right
• click on the node and then on the canvas a few times (sometimes needed)
• observe that the node now is resized to contain all text.

Changing the text alignment back to center breaks the node again.
