Summary	0036257: Simply selecting literally anything at all in the object inspector causes the entire active design form to be redrawn
Description	It basically seems like one of the mouse events (possibly "OnMouseDown"?) of the object inspector is set to just blindly redraw the design form in all cases, no matter what, regardless of whether or not any properties are actually modified. Apart from causing very noticeable overall sluggishness (possibly part of what I was talking about in issue 36218), this causes things like the focus for all of the TEdit text rows in the inspector (such as "Hint", or "Caption", and so on) to be immediately lost after being selected, which in turn makes the text caret disappear from them. It's just way, way, way too much redrawing.
Steps To Reproduce	Use the object inspector in any way.

Juha Manninen 2019-11-05 13:52 developer ~0119074	Do you mean this happens without Sparta Docked Form Editor?

Akira1364 2020-02-13 17:31 reporter ~0121084	I'm not sure. I'll have to check. Apologies for not coming back to respond for a while.
