Add a shadow to the bottom side of the sticky widget

[ptsl]

Hello, Ayu Mirage has been my favorite VSCode and Sublime Text theme since I first discovered it.

However, on VSCode, it does not work nicely with Sticky Scroll.

Problem Description

1. Go to the VSCode menu. Enable View -> Sticky Scroll.

This enables the sticky scroll widget. This widget always shows the current class and method.

2. Go to Settings (Ctrl+,).
3. Go to Editor > Sticky Scroll: Default Model.
4. Try all settings. The last setting (indentationModel) will make the sticky window as tall as possible.

Now, there is no line showing the border between the sticky widget and the rest of the editor. There is nothing to show that some lines of the function definition are missing, save for the gap in line numbers. (Line 54 is followed by Line 65 and then by Line 77.)

Please, add a shadow to the bottom side of the sticky widget (<div class="sticky-widget">). For your inspiration... I've filed a similar issue to Yi Dark & Yi Light Themes and this is how they fixed it:

Anyway, I said, this is just for inspiration and there are other solutions. For example, Dark High Contrast theme adds a simple line. Or a different background can be used for the sticky widget, just to give you a few ideas.
