It's expected that the page title will be based on the last or initial filters. Filters from product/SKU specifications are always set as the last one from the breadcrumb, which takes place as the page title.

In cases of a full-text search, the specification value that is alphabetically less than the searched term, but the closest to this searched term, will take priority as the title. For example, if you search for jeans and filters by size=G and then material=Chiffon, the size G will take priority as a page title.

Simulation

Navigating in a page like "/summer-2024?map=productclusternames" and applying any filter that is not an SKU specification will keep the page title as "Summer 2024", but a filter like "size=M" will take priority and the title will be shown as "M".
