Stop Visio from Jumping to Center of Text Box

I have some Visio drawings with large text boxes in the first couple of tabs. These text boxes have tabular data that we format with tabs and tab stops. The problem is any time I double-click on the text box Visio jumps to the center of the text box. When I try to adjust the tab stops Visio automatically jumps back down to the middle of the text box which pulls the tab stop off of the ruler causing it to be deleted. I've tried zooming out so I see the whole text box but Visio zooms back in when I double-click on the box and the ruler is not visible from the center of text box. I've also tried reducing the size of the text box and let the text flow over the bottom but I see the same behavior. I cannot edit the tabs on these text boxes.

My work-around has been to duplicate the text box, delete all but the top line, then use the format painter to apply the tabs to the original text box. The format painter applies the formatting of the first line to the whole text box so every time I adjust the tabs I have to re-format the text in the box. Embedding Excel is not an option.

How do I prevent Visio from jumping to the center of the text box every time I open it or adjust the tabs?

Windows 10 Enterprise version 21H2 / Visio Plan 2 MSO (16.0.13801.21148) 32-bit
