Debugger => Some variable content popup issues

During debugging, VsCode has three quick possibilities to show the detailed content of variables (as far as I know):

1. The file edit area: For each line the content of the variables in this line are shown which is very nice. With mouse hovering over this area a popup appears with a bigger, multiline view of these contents, which is even nicer. As far as I know, this is currently the only way to have a fast multiline content view during debugging.

I have found these issues with it:

• You can see in the image that the variables content goes over two lines. The popup appears by hovering both over the first line and the second. With the first line everything is fine, but when I trigger the popup from the second line the popup appears a bit higher as the mouse pointer (i.e. at the first line, which is the corresponding code line). If I then move the mouse in order to select some popup text or just want to scroll, the popup disappears immediately. You can go with the mouse 'into' the popup if it was triggered from the first line only
• It is currently impossible to select all text from the popup if the text doesn't fit into the area, i.e. there is a scrollbar. If I want to select with the mouse, the popup disappears if I move over the border of the popup instead of scrolling and selecting more text. If I want to select everything with 'ctrl+a', it selects the code inside the file edit area instead
• The toString() content of a variable is only shown if someone clicks on the 'click to expand' eye-button for this variable inside the variables view. It would be VERY useful if this button could also appear inside this popup. This is the button of the variables view:

2. In the variables view: There also a popup appears. Sadly this is not multiline, the size can not be adjusted, it is only useful for really small content as numbers or small strings, and small content is shown directly inside the variable view anyway. It would be preferable to have the same or a similar popup as inside the edit area

3. When hovering over a variable inside the file edit area: Here, the content is shown similar as in the variables view. It would be nice if there is a possibility to see multiline content also. E.g. with the same or similar popup as in 1.

Empieza reproduciendo el comportamiento de los popups descrito en el issue en el área de edición de archivos, la vista de variables y al pasar el cursor sobre una variable. Compara la posición de los popups, su cierre al seleccionar o desplazarse, el tamaño con varias líneas y el control de expansión de toString que falta. Se considera completado cuando los popups afectados admiten de forma coherente la interacción solicitada con varias líneas y muestran la acción de expansión cuando corresponde.
