runs, the count fluctuated between ~280 and ~281, causing the\ntest to
fail intermittently.\n\n### Reasoning\nThe failing test screenshot
showed a slightly different zoom level\ncompared to the local FTR
environment.\nTo stabilize the test, I explicitly set the zoom level at
the beginning\nof the test to ensure consistent MVT data
loading.","sha":"7943c3e3f3e145a94c985d5aca1a08ee51360610","branchLabelMapping":{"^v9.3.0$":"main","^v(\\d+).(\\d+).\\d+$":"$1.$2"}},"sourcePullRequest":{"labels":["Team:Presentation","loe:small","technical
