Discovered while testing MC-277670.
The bug
If an invalid texture is used for a text character, the missing glyph will replace it. However, the character will still behave as though it has the expected size from the provided texture file.
How to reproduce
A resource pack is attached to this ticket that replaces "A" with a 257-wide, 1-high texture, and "a" with a 1-wide, 257-high texture. Both of these exceed the maximum dimensions for a font character.
Download and apply the attached resource pack
Observe the letters "A" and "a" in context
Optionally compare to a character with no defined glyph:
Expected results
These would appear as normal missing glyphs.
Actual results
"A" causes a huge gap after itself, and "a" bleeds into the next character.
How to fix
When making these use the missing glyph, it should also set the dimensions to the correct value.

After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
