How to make TraditionalForm display the same in the Manipulate output as in a notebook?

Question

I noticed that TraditionalForm does not display as nice in the Manipulate output as in normal notebook. Is there a way to make it look the same?

Here is an example,

Manipulate[
TraditionalForm[-Derivative[2, 0][u][x, y]-Derivative[0, 2][u][x, y] == f[x, y]],
 {z, None}
]

and compare the output above to the same command, but without the Manipulate wrapper:

TraditionalForm[-Derivative[2, 0][u][x, y]-Derivative[0, 2][u][x, y] == f[x, y]]

Here is the output, side by side. (left side is the Manipulate output).

There might be an option to correct this inside Manipulate? Will keep looking. But meanwhile, any one knows why that is?

btw, I found that by Rasterizing it, it looks close to the notebook, but need to work on the resolution little:

Manipulate[
 Rasterize@
  TraditionalForm[-Derivative[2, 0][u][x, y] - 
     Derivative[0, 2][u][x, y] == f[x, y]],
 {z, None}
 ]

thanks

Answer 1

This is just a matter of different style (font here). This will produce identical output to what you get outside of Manipulate:

Manipulate[
    Style[
        TraditionalForm[-Derivative[2, 0][u][x, y] - Derivative[0, 2][u][x, y] == f[x, y]], 
        FontFamily -> "Times"
    ], 
    {z, None}]

Answer 2

Just stumbled upon this and thought it's worth adding something here: To avoid having to specify the style for every instance of TraditionalForm output in your Manipulate, you could spell out the font in the BaseStyle option, i.e.:

SetOptions[Manipulate, BaseStyle -> {FontFamily -> "Times New Roman"}];

Manipulate[
 TraditionalForm[-Derivative[2, 0][u][x, y] - 
    Derivative[0, 2][u][x, y] == f[x, y]], {z, None}]
