it's an overflow. if the value is greater than 255 (which is the highest number possible with one byte of binary,) the game will treat it like a negative number.
Comments from MCPE-64542:
When I used /effect @s strength 99999 73
I got strength level 73 and could not attack any enemies
I could attack enemies when using /effect @s strength 99999 72
I tried strength level 80 , 90, 100 , 200 and 255 but also could not attack any enemies
But when I tried strength level 1-10,20,30,40,50,60,70-72 , i could attack enemies
Guys what are you doing with the insane strength levels? Strength 20 is enough to one-shot the Wither with your bare hands.
Justerfrog is probably right that there is an overflow happeneing, but it isn't at damage = 255. For strength level 61 it's at the damage = 32 million mark.
Here is a spreadsheet.

personally I find this feature to be quite useful for disabling entities from dealing damage. Weakness 255 does not work if you are holding a high sharpness diamond sword, for example. I hope this doesnt get fixed, it doesnt negatively affect gameplay either. Strength 20 is plenty.
Bedrock is still using the outdated strength formula. And presumably, is still using outdated integers for health/damage?
When you have strength level 50 (51) applied, it stops dealing damage to mobs; the mob acts like if it got hurt, but doesn't receive any damage (I know this because it occurred with the wither that has a boss bar). So if your doing a sword fight with crazy strength effects, just make sure you use something under level 40-45.
@tryashtar: Yes, Bedrock uses integers for health and damage. For example, a creeper or armorless skeleton takes 10 punches to kill (2 dmg/punch), but an unarmored zombie takes 20 punches to kill due to the zombie's 2 natural armor points. Even though the zombie armor points should only reduce damage by 8% (= .16 for a punch), the actual damage value is truncated/rounded down to the nearest integer. In other words,
FLOOR( 2 - ( 2 * 2 *.04 ) ) = 1However, according to MCPE-34981 Bedrock doesn't use the orginal strength formula of +( 130% * level ), even though that is still shown in the tooltip. What it actually uses is a recursive function,
Damage @ Str_Level = FLOOR( ( Damgage @ (Str_Level - 1) ) * 1.3 + 1)The fact that it's recursive is why the damage values get insanely high very quickly.
Affects 1.17.10. Opposite effect occurs with high levels of weakness (mobs deal damage).
This problem applies to all entities, including mobs. If you give, for example, a zombie 255 the strength effect and he attacks you, you will not receive damage.
Affects 1.18.1
Affects 1.18.10. There are two possible results to this: 1. The mob appears to take damage, but does not take any damage. 2. You are unable to hit the mob at all (the mob does not even appear to be damaged). This seems to happen with lower and higher levels of Strength respectively.
Resolved at some point during or before 1.18.31.
