Auto completion is strange

[X-Ryl669]

For example, in C++

#include <iostream>

int main()
{
   std::cou <HERE>

Try to complete std::cout. The proposed choice removes the typed 'u'. You can't iterate on the completions either, if you press Ctrl + Space, the line is indented instead.
I don't think Ctrl+Space should ever trigger a "tab" command.

Yet, this works:

#include <iostream>

struct T
{
   void onSomething() {}
   void onReturn() {}
}

int main()
{
   T t;
   t.on <HERE>

Here, you can iterate the 2 choices... But if you validate the completion by pressing right key, sometimes (not everytime), a additional space is added after the completion. Pressing "tab" only indent the line

Finally, if autoCompleteDetails is true, it opens a pane with only the function return type or a lot of empty lines like this:

  1 #include <iostream>
   2
   3 class Test{
   4 public:
   5     void test(){
   6         std::cout<<"Test"<<std::endl;
   7     }
   8     void test2() {}
   9 };
  10
>>11 int main(){
  12     Test test;
  13     test.test2 (test)// After pressing Ctrl+Space here completion event should be triggered but nothing happens
>>14     return 0;
  15 }
>>16

For me, when I press Ctrl+Spacebar, the text which I typed disappears.
Following is my setup

• lsp - 0,6.2
• micro - 2.0.13
• os - Ubuntu 22.04
• lsp.server - clangd

Say for example, I type std::cou and press Ctrl+Spacebar then I am only left with std::
