DESCRIPTION

I found a suspected memory leak bug in KDE Plasma's KRunner, which leads to
system memory exhaustion. It doesn't seem to be caused by plugins and might be
a defect in the core component. (This report was translated using AI, and there
may be grammatical errors. My apologies!)

STEPS TO REPRODUCE

1. Launch KRunner.  
2. Enter any string (it seems that Asian languages are more likely to trigger
the issue?).  
3. Press the Page Up key (or press Ctrl+A to select all, then press Page Up).  

OBSERVED RESULT

Memory usage increases rapidly until the system memory is exhausted.

EXPECTED RESULT

Move the keyboard input cursor to the beginning or ignore the input from the
Page Up key.
