Before this commit, the t-lang on a t-call was not propagated into the context's of the callee template It resulted into mismatch translation and formatting in the final rendered template i.e. having a t-esc with a qweb widget float would take the wrong float format After this commit, the t-lang parameter alters the context of the template and t-esc with widgets are translated OPW 1939989 closes odoo/odoo#31291
