Seen on client versions 4.18.0 and 4.19.0-4003 on Fedora42 with server build #4115 on RHEL10. Translations for "Filename" that overflows are for languages Spanish, French, and Portuguese (BR). This string appears to gone through a bit of changing in the past. Bug 4087 introduced translations for the file chooser dialog (commit r24168). During this development, it was pointed out (see bug 4087 comment #2) that these translations overflow, which lead to the use of "Name" instead (see commit r25308). Later in bug 4482, "Filename" and a couple of other strings that all went by "Name" were differentiated better in commit r27180, which lead to the return of the "Filename" label with corresponding translations in commit r27420.
