It's been a longstanding issue in Minecraft that renaming blocks loses the name when you try to do anything with them (see MC-209 with two dozen dupes). Being able to rename a block then place it is considered "works as intended" but anvils should give some kind of warning to the user that the custom name will not be preserved, as this behavior is non-obvious to anyone not familiar with all of Minecraft's quirks.
Note: this is not a bug complaining that blocks lose their names and is not a duplicate of MC-209, this is a bug specifically about how anvils don't warn you ahead of time.

I'm well aware of Reddit thanks. A warning that you're going to lose information isn't exactly a "feature request".
