If you use the edit frame to do a uniform scale up or down it's not really particularly relevant which specific orientation the edit frame has right then, it will do a uniform scale from the bounding box center and that should not do anything that I'd term "squashing" to the curve.

It would only get skewed (in rotation, which you can then adjust by grabbing the rotation handle) if you track along one of the x or y directions of the edit frame which does a one-directional scale instead of a uniform scale. But you can solve this by just moving your mouse some distance away from those one-directional scale tracking lines and that will then "shake off" the one directional scaling and do uniform scaling instead.

Here's an example - notice how after I "shake off" the one directional tracking that it then does a uniform scale which should not squash your curve at all:
