Japanese input stutters when note contains over 5 blocks

[AkaneAwsl]

Describe the bug

Short

• When note contains over 5 blocks
• and I write sentence that too long and wrapped itself
• My Japanese Input gets cut off
• Sorry for my bad eng

Detail

Japanese input is different from English input
For example, if you want to type "ツ", you have to type "tsu" (and convert to katakana)
but in FleetingNoteApp, sometimes I can't type correctly

Same thing happens

• even if window size is narrow as possible
  • so I don't think it matters how many characters there are
• it happens with Kana input as well
• It happens if every characters weren't 2byte
  

How it should be

Unless note contains over 5 blocks, it works completely well
It's perfect if I could do same thing on long notes (that contains 5 blocks),

About mobile

It doesn't happen on my iPhone, so it should be ok. I guess.

It may be needless to say

• I'm sorry if something wrong
• I know no one cares about Japanese language
  • but I'm glad if you could fix this
