   Thanks for digging into this with multiple approaches.
   
   Do we agree that `focus()` should run only **after** the modal is fully 
closed?
   If so, what do you think about triggering 
`this.messageService.paragraphRemove(this.paragraph.id)` after the modal closes?
   
   I confirmed that the return value of `nzOnOk()` is emitted to `afterClose` 
subject. Using that, we can run the paragraph removal (including `focus()` to 
the appropriate paragraph) once the modal is definitely closed. This worked in 
my local testing(tested version: 
https://github.com/tbonelee/zeppelin/commit/7a64b2eb0613543001dd05da6390f8bda7cb9322).
   
   Could you review this approace and share your thoughts?
   ```diff
   -        this.nzModalService.confirm({
   -          nzTitle: 'Delete Paragraph',
   -          nzContent: 'Do you want to delete this paragraph?',
   -          nzAutofocus: null,
   -          nzOnOk: () => {
   -            this.messageService.paragraphRemove(this.paragraph.id);
   -            this.cdr.markForCheck();
   -          }
   -        });
   +        this.nzModalService
   +          .confirm({
   +            nzTitle: 'Delete Paragraph',
   +            nzContent: 'Do you want to delete this paragraph?',
   +            nzOnOk: () => true
   +          })
   +          .afterClose.pipe(takeUntil(this.destroy$))
   +          .subscribe(result => {
   +             // result is undefined if a user cancels
   +            if (result) {
   +              this.messageService.paragraphRemove(this.paragraph.id);
   +              this.cdr.markForCheck();
   +            }
   +          });
