            Bug ID: 504373
           Summary: Konsole uses 100% CPU when "find" feature used
    Classification: Applications
           Product: konsole
      Version First 25.04.0
       Reported In:
          Platform: Fedora RPMs

  Target Milestone: ---

STEPS TO REPRODUCE
1. Open konsole
2. Press CTRL + SHIFT + F or click "Find"
3. Type anything that is NOT in the konsole
(At this point; CPU usage on 1 thread spikes to 100%)
Optionally:
4. Create new tab with `CTRL + SHIFT + T`
5. Try to close or detach the old tab
Konsole crashes

ADDITIONAL INFORMATION
When I launch konsole with `strace`, it spams this when CPU usage spikes to
100%
```
ppoll([{fd=5, events=POLLIN}, {fd=36, events=POLLIN}, {fd=38, events=POLLIN},
{fd=41, events=POLLIN}, {fd=54, events=POLLIN}, {fd=56, events=POLLIN}, {fd=66,
events=POLLIN}], 7, {tv_sec=0, tv_nsec=0}, NULL, 8) = 0 (Timeout)
```
