Scale, rotate & create areas tool: bottom toolbar unusable to view angle/scale factor/offset measurement

[Squizie3]

This bug is very similar to #19887: after the update to stable release 17084 which included the enhancement #19830, you can't properly view the measurement of the action you're doing anymore, instead the length of the way you're performing the action on is shown. While for the parallel ways tool this should now be fixed, I discovered the bug also exists for the scale, rotate and create areas tools (and maybe even more). That last one works correctly for it's default tool behaviour, but not when you need to perform actions using the Ctrl button pressed.

What steps will reproduce the problem?

Rotation tool:

1. Activate the selection tool in the sidebar
2. Use the keyboard shortcut combination to activate the rotation tool (usually Ctrl+Shift)
3. Start rotating a random object
4. You cannot see any angle measurement like before. It used to show values in degrees in one of the bottom status bar's boxes (don't know exactly which one in particular anymore).

Scale tool:

1. Activate the selection tool in the sidebar
2. Use the keyboard shortcut combination to activate the scale tool (usually Ctrl+Alt)
3. Start scaling a random object
4. You cannot see any scale factor measurement like before. If I'm correct (not entirely sure about this one to be honest), it used to show values of what factor you were scaling at (e.g. 0.87) in one of the bottom status bar's boxes (don't know exactly which one in particular anymore).

Create areas tool:

1. Make sure you are in 'expert mode' in JOSM's preferences
2. Activate the create areas tool in the sidebar
3. Press the Ctrl key (to move nodes or line segments, instead of the default tool's behaviour)
4. Start moving a random object, being it a node you're moving alongside one of it's connecting lines, or a line segment.
5. Watch the bottom status bar's measurement box flicker.

What is the expected result?

Showing the angle, scale factor or offset measurement from the tools you're using.

What happens instead?

The angle or scale factors aren't visible at all, the offset measurement flickers and is constantly overwritten by the way's length.

Please provide any additional information below. Attach a screenshot if possible.

Please take a look at #19887 for a very similar problem, that should now have been resolved.
