Make editor hover less intrusive

[per1234]

Is your feature request related to a problem? Please describe.

The editor hover seems unnecessarily large. It covers up a lot of the code, which is especially annoying/distracting when it is triggered inadvertently.

Describe the solution you'd like

• Make the font size of the title the same as the editor font.
• Remove the unnecessary vertical padding from the title.

Environment

OS: Windows 10
Version: 2.0.0-beta.2-snapshot.298cc11
Date: 2021-02-15T14:16:52.603Z
CLI Version: 0.16.0 alpha [c977a238]

Additional context

I also notice there are some strange horizontal rules in the hover that don't have any alignment with the text.

Would be nice to be able to set the delay time prior to pop-up, it's now in my opinion way too short...

the IDE is currently unusable as the pop ups just get in the way if you edit with the mouse.

Regarding these:

• Make the font size of the title the same as the editor font.
• Remove the unnecessary vertical padding from the title.

Some time back, Akos kindly helped me to understand this situation better. I forgot to post an update to the issue after that though so I will do that now:

The formatting for the hover text is provided by the clangd C++ language server used by the Arduino Language Server. For the example used here, it looks like this:

{
  "id": 11,
  "jsonrpc": "2.0",
  "result": {
    "contents": {
      "kind": "markdown",
      "value": "### function `pinMode`  \n\n---\n→ `void`  \nParameters:  \n- `uint8_t pin`\n- `uint8_t mode`\n\n---\n```cpp\nvoid pinMode(uint8_t pin, uint8_t mode)\n```"
    },
    "range": {
      "end": { "character": 9, "line": 34 },
      "start": { "character": 2, "line": 34 }
    }
  }
}

So the large font size of the first line of the hover results from the rendering of the H3 heading (as specified by the Markdown markup ###).

VS Code with the clangd extension produces an identical intrusive hover for C++ code:

I have no problem with the popup on hover, it takes for me too much time to display it.
