SUMMARY
Auto completion erases the leading space after '<' or '>' in if statement when
using clangd as lsp server.
However when I disable lsp, it works well.
Get more detail from
https://discuss.kde.org/t/why-auto-completion-after-or-erases-the-leading-spaces-in-kate/38284.
STEPS TO REPRODUCE
1. launch kate and enable clangd as lsp server
2. write c++ code like:
```c++
int abcde = 1;
if (1 ) {
```
3. type '<' and a space in if statement, then type 'a' and press TAB to
complete the code
OBSERVED RESULT
the space after '<' was erased
EXPECTED RESULT
keep the space after '<'
