Programmatically set exposed filter not possible when also using contextual filter

I’ve got a view, that needs to set the default value for an exposed filter based on a user entity field. This basically works:

function MYMODULE_views_pre_build(DrupalviewsViewExecutable $view) {   if ($view->current_display !== 'MY_VIEW_DISPLAY') {     return;   }   $exposedFilterValues = $view->getExposedInput();   if (!array_key_exists('MY_FIELD', $exposedFilterValues)) {     $personalizedDefaultValue = $someUserEntity->getMyCustomDefaultFilterValue();     $view->setExposedInput(array_merge($exposedFilterValues, ['MY_FIELD' => $personalizedDefaultValue] );     $view->element['#cache']['tags'] = Cache::mergeTags($view->element['#cache']['tags'] ?? [], $someUserEntity->getCacheTags());   } }

BUT:

This views page also has a contextual filter filtering a completely different field. As soon as a contextual filter value is present in the URL, the code above is still executed, but it has no effect on the frontend. Without a contextual filter value, it works perfectly.

Why doesn’t the code for the exposed field work when a completely different field’s contextual value exists?
