Changing the base scale does not modify the coordinates.

Also I notice a bug that didn’t happen on v39.5: when we toggle Base scale below 100% and the image ends up still being bigger than the window, you are still able to move inside the window when you should not to because the option is set to not move inside the window. (it fixes if you move to another page)

The problem is that when you change the scale to something like 80% and the image is still bigger than the window, it doesn’t adjust according to the limited range like v39.5 did, it instead shows up black bars and you have to manually move inside the window (scroll up or down or change the page) in order to fix it.

v39.5 never showed black bars because it adjusted the position automatically. Something is not right

基底スケールの変更を純粋にスケールのみの変更として座標の更新をしないようにしたことによる現象。v39.5では基底スケールの変更と同時に座標補正を行っていたが、同時に座標がリセットされるという問題もあった。

どうするか要検討。

Phenomenon due to the fact that the change in base scale is purely a change in scale only, with no update of coordinates. In v39.5, coordinate correction was performed at the same time as changing the base scale, but there was also a problem that coordinates were reset at the same time.

Need to consider what to do.
